Liam Payne kicked off at airline staff after his flight was delayed due to a bomb threat.
The One Direction hunk reportedly shocked fellow passengers when he began "swearing up a storm" during the flight from Puerto Rico to Philadelphia over the weekend.
According to the Daily Mirror newspaper, the 20-year-old singer became angry after being told there was a four-hour delay because he was eager to see his girlfriend Sophia Smith, who celebrated her 20th birthday yesterday (09.02.14).
A source said: "Liam was livid. He was tired and grumpy, and just wanted to get home because it was his girlfriend's birthday. He snapped at officials and started swearing. Everyone was quite taken aback."
But the star started to calm down when he realised he wasn't the only passenger annoyed that the US Airways flight 770 was grounded at 1.30pm.
The source added: "He apologised soon after. He didn't mean any offence."
However, fan Brooklyn Wiles was not impressed by Liam's outburst and claimed he refused to smile when she asked for a photograph after the drama.
She posted on Twitter: "I love One Direction ... but for him to act like a complete jerk because of a flight that was delayed due to a bomb threat?!?
"Every single person on that plane has to deal with this too... we all are trying to find flights and get home. And he was swearing up a storm. He was a nobody three years ago...
"Just because you're famous doesn't mean you should be a jerk to your fans.
"It's hard to love someone who takes fame too far. Liam Payne, I've lost my respect. (sic)"
The flight finally took off at 5.18pm after a passenger made the bomb threat and police found no explosives on the plane.

Marc Anthony and Chloe Green have reportedly split up again.
The on/off couple, who first started dating in February 2013, decided to end their romance recently but friends haven't ruled out reconciliation.
An insider told UsMagazine.com: "They are taking a break. It is because of busy schedules."
The duo briefly split last April but reunited in June before jetting off on holiday to St. Tropez in France.
A source said at the time: "The pair got serious very quickly and had the blessing of her parents, but it hasn't worked out. It seems to have been Marc's decision to end it."
The 45-year-old singer and the 22-year-old British Topshop heiress were last seen together at the Grammy Awards in Los Angeles on January 26.
Marc, who has five-year-old twins Max and Emme with his ex-wife Jennifer Lopez, began seeing Chloe shortly after splitting from model Shannon De Lima in January 2013.
The Latin heartthrob also has two sons, Cristian, 13, and Ryan, 11, with his ex-wife Dayanara Torres, and a 19-year-old daughter, Ariana, with his ex-girlfriend Debbie Rosado.

Joe Jonas' new niece has brought his family closer together.
The 24-year-old singer and his brothers, Kevin, 26, and Nick, 21, sparked rumours of a bitter feud when they announced the end of their group, The Jonas Brothers, in October, but his older brother's newborn daughter, Alena Rose, has reinforced their bond.
He told E! News: "I don't want to sound cheesy saying that but you just want to spend more time with each other and you're just excited for the next chapter for each other's lives."
He added: "I'm so happy for them. I mean he is a dad now and it's kind crazy."
Kevin and his wife, Danielle, welcomed their first child into the world last Sunday (02.02.14), and Joe was scared to hold the tot after meeting her for the first time.
He said: "She is so tiny, it kind of scares me. She was awake, kicking and smiling and grabbing for your finger."
The heartthrob said it is "mind blowing" to have a new addition to their family and really "exciting."
He added: "I honestly can't wait to spend more time with her."
But Joe, who is dating model Blanda Eggenschwiler, has no desire to settle down himself just yet.
He said: "I will take my time. I will take my time with running around and having my fun. Down the road."

Nick Carter reportedly snubbed his sister's wedding.
The Backstreet Boys star was expected to walk his younger sibling, Angel, down the aisle at her wedding to Corey Conrad at Newhall Mansion in Piru, California on Saturday (08.02.14), but opted to celebrate his own upcoming nuptials in Las Vegas instead.
The 'Everybody' hitmaker, 34, was noticeably absent from the ceremony, according to UsMagazine.com, but 26-year-old Angel's twin brother, Aaron Carter, was on hand to escort her on his own.
Meanwhile, Nick and his bride-to-be, Lauren Kitt, celebrated at a joint bachelor and bachelorette party at the Palms Hotel and Ghost Bar with approximately 15 friends.
The singer was clearly looking forward to the event as he shared a picture of their gift bags and champagne on Twitter on Friday (07.02.14), with the caption: "It's about to go down at @palms just entered the room of ecstasy."
Nick previously admitted his relationship with his family "has been toxic" at times and even claimed they blamed him for the death of his younger sister Leslie from an overdose in 2012.
The heartthrob skipped her funeral in favour of performing a scheduled concert and later told the 'Dr. Phil' show: "The communication is something that I'm still to this day trying to work on. ... It's tough when you come from a background like that and a home that is really up and down and roller-coaster."

Jessica Alba gave Gwen Stefani a hamper of "practical items" for her baby shower.
The No Doubt singer, who is expecting a baby boy with her husband, Gavin Rossdale, in the near future, was treated to lots of luxurious gifts by her pals, including Gwyneth Paltrow, Kate Beckinsale and Nicole Richie, as she celebrated the impending arrival of her third child at the Hotel Bel Air in Los Angeles on Saturday (08.02.14).
A source told E! News that Jessica, who has daughters Honour, five, and two-year-old Haven, opted to give the 'Settle Down' hitmaker a "dinosaur storage bin full of toys, books and clothes," along with a $125 diaper cake from her brand The Honest Company, filled with organic goodies, including bubble bath, body lotion, healing balm and 92 diapers.
An insider also told PEOPLE.com: "She had tons of items picked out and put in a huge 3Sprouts dinosaur basket from Bel Bambini. She filled it with practical items."
Gwen looked "radiant" at the party and a friend said: "As she walked over the bridge and joined her friends she had a big smile on her face and was giving everyone hugs. There was a big welcome cheer for her and she seemed very grateful for all of the love."
The blonde beauty, who already has sons Kingston, seven, and Zuma, five, also received lots of designer gifts.
A source said: "Other guests brought baby clothes from Chanel and Bonpoint. There were tons of gifts that were all wheeled out on a luggage cart and put in Gwen's car."

Gareth Gates was voted off 'Dancing on Ice All-Stars' tonight (09.02.14).
The 29-year-old singer, who first rose to fame on 'Pop Idol' in 2002, became the latest star to leave the ITV series after losing a skate-off against former 'EastEnders' star Sam Attwater.
Despite impressing judges Jason Gardiner, Ashley Roberts, Robin Cousins and Karen Barber with his performance to Wham!'s hit 'Freedom,' during which he wore a George Michael-style blonde wig, Gareth and his professional partner, Brianne Delcourt, failed to win them over with their follow up routine to U2's 'Beautiful Day.'
All four judges chose to save 28-year-old Sam.
Upon hearing the result, the modest star - who is also appearing on 'The Big Reunion' as part of boy band 5th Story - gave credit to his partner as he departed the rink.
He said: "Never mind, it has been amazing and I would like to thank this amazing lady Brianne. Bless you all, thank you."
Delcourt said that the singer had been a "pleasure to work with".
'Dancing on Ice All-Stars,' which is the show's final series, continues next Sunday (February 16) at 6.15pm on ITV.

Shia LaBeouf wore a brown paper bag over his head to the German premiere of his new movie.
The 27-year-old actor, who announced he was retiring from "all public life" last month, refused to show his face at a red carpet screening of 'Nymphomaniac' in Berlin on Sunday night (09.02.14).
He cut two eye-holes into the bag and wrote the words "I'm Not Famous Anymore" in black capital letters on it before placing it over his head and attending the event in a dapper tuxedo, according to gossip website TMZ.com.
The 'Transformers' star was clearly eager to make a statement just an hour after storming out of a press conference for the movie.
When asked if it was uncomfortable filming sex scenes for the film, Shia let his co-star Stacy Martin answer first.
After hesitating for a moment, the dishevelled-looking star, who was missing a bottom tooth, then quoted retired French soccer player Eric Cantona's famous words to answer unwanted media attention: "When the seagulls follow the trawler, it's because they think sardines will be thrown into the sea. Thank you very much."
He then walked off stage much to the amusement of Stacy.
Shia announced in January that he was taking a step back from the limelight after he was forced to apologise for plagiarising author Daniel Clowes' graphic novellas, 'Justin M. Damiano,' for his short film 'HowardCantour.com'.
He wrote on Twitter: "In light of the recent attacks against my artistic integrity, I am retiring from all public life."
He added: "My love goes out to those who have supported me. #stopcreating."

Victoria Beckham received a special good luck note before her fashion show.
The former Spice Girl was sent a "beautiful message" from her husband, David Beckham, and their four children, Brooklyn, 14, Romeo, 11, Cruz, eight, and two-year-old Harper before presenting her latest collection at New York Fashion Week on Sunday (09.02.14).
The 39-year-old designer took a snap of the well-wishes, which read: "Good luck Mommy, love David, Brooklyn, Romeo, Cruz and Harper xxxxx," and shared it on Twitter, with the caption: "Beautiful message from my babies x vb."
The brunette beauty clearly appreciated the support of her family as David, 38, and their children also had front row seats at the presentation.
Although the Beckham clan currently live in London, the retired footballer recently sparked speculation they could relocate to Miami, Florida in the future after he announced he is launching a Major League Soccer club there.
Speaking at a press conference earlier this week, he said: "This is an exciting time for myself, family and friends. We're really looking forward to bringing this to Miami."
A spokesperson for the star also told the MailOnline website: "Victoria and the children are thrilled by this next adventure in their life story, as a family they love America and are all very excited to explore a new city and spend time in beautiful Miami."

Jennifer Hudson has learnt to embrace her figure.
The 'Feeling Good' hitmaker, who lost 80 pounds after first signing up as a Weight Watchers spokesperson a few years ago, admits she no longer feels self-conscious on the red carpet.
Wearing a short white dress with a plunging neckline, the 32-year-old star told USA Today newspaper at the BET Honours 2014 in Washington D.C. on Saturday night (08.02.14): "You need to embrace yourself, find those things that you love about yourself and know that no one is like you, and own being you."
Jennifer recently admitted she is much more comfortable with who she is since entering her thirties.
She said: "I love the thirties. I'm like, now I got the hang of it and being settled with myself and embracing it. I love the space that I'm in."
Meanwhile, rapper and actor Ice Cube, legendary singer Aretha Franklin, Motown founder and visionary Berry Gordy, photographer Carrie Mae Weems and American Express CEO Kenneth Chenault were among those honoured at the annual event.
Mariah Carey wowed the audience by performing her new single, 'You're Mine,' for the first time in a black, cleavage-baring dress atop a piano.
Hosted by 'How I Met Your Mother' star Wayne Brady, the BET Honours will air February 24 on BET.

Justin Bieber was allegedly speeding hours before he was arrested in Miami last month.
The 19-year-old star was charged with driving under the influence (DUI), resisting arrest and driving with an invalid licence on January 23, but the singer's yellow rented Lamborghini reached 136 MPH at 1.23 a.m., long before he was pulled over by police shortly after 4 a.m.
According to data, obtained by TMZ.com, from the car's built-in GPS tracking system, which recorded its speed and location at all times, the vehicle clocked 108 MPH on the Julia Tuttle Causeway in Miami Beach and accelerated to 136 MPH within a minute while being driven to Set nightclub, where the singer arrived at 2.27 a.m. and partied for an hour before leaving.
But the data also shows that Justin was cruising under the speed limit at 27 MPH when he was arrested and accused of drag racing at between 55 and 60 MPH for 15 blocks.
The 'Heartbreaker' hitmaker is set to appear in court in Florida in relation to the charges on March 3.
Justin's lawyer Roy Black has already filed a written plea of not guilty.
Meanwhile, his lawyers are fighting to stop half-naked pictures of the star in police custody being published.
The images were taken when he was arrested and sources say they expose "intimate" parts of his body.

Gwen Stefani enjoyed a star-studded baby shower on Saturday (08.02.14).
The No Doubt rocker, who recently confirmed she is expecting another baby boy with her husband Gavin Rossdale, was joined by her close friends, including Gwyneth Paltrow, Kate Beckinsale, Jessica Alba and Nicole Richie, for the blue-themed bash at the Hotel Bel Air in Los Angeles.
A source told UsMagazine.com: "People cheered as soon as she walked in.
"There were lots of people laughing and it seemed like everyone was having a lot of fun. It was very lively!"
The blonde beauty, 44, arrived with Gwyneth and was ushered into a private room that was decorated with light blue lights, bouquets of white hydrangeas, a banner that said "SWEET," and "guests were greeted with glasses of red or white wine."
Other guests at the afternoon tea party included chat show host Chelsea Handler, celebrity stylist Rachel Zoe and Tobey Maguire's jewellery designer wife, Jen Meyer.
Gwen posted a photograph of a table of blue sweet treats at the event on her Instagram page on Saturday, with the caption: "Baby shower!!! #can't believe im pregs thanku Shelli Azoff for a beautiful #girlyday =blessed (sic)"

Bruce Willis whisked Emma Heming-Willis away on a babymoon ahead of the birth of their second child.
The 'Diehard' star and his 35-year-old model wife, who are already parents to daughter Mabel, 21 months, recently returned from a romantic trip to the Turks and Caicos Islands, where the 58-year-old actor owns a home.
An insider told UsMagazine.com: "The babymoon was at Bruce's place in Parrot Cay."
Emma posted a photograph of herself looking happy and relaxed on the beach during their holiday on her Facebook page with the caption: "#BabyMoon 2014 Photo: B. Willis"
She also shared a picture of her famous husband flying a kite on the beach and wrote: "A man with many hidden talents #KiteFlying"
It was first revealed in December that the couple, who married five years ago, are expecting another baby.
Bruce also has three daughters, Rumer, 25, Scout, 22, and Tallulah, 20, with his ex-wife Demi Moore, and the source suggested the actor wouldn't mind having another baby girl.
The insider said: "[Bruce is] adorable with Mabel and all of his girls. It's hilarious to see the tough guy stereotype just melt away. He'll put on a baby voice, get cute with her. Being a dad is no doubt the most important thing for him."
Emma appears to be equally close to Bruce's other daughters as shortly after returning from their holiday, the couple helped Tallulah celebrate her birthday in New York City.
The brunette beauty shared a photo of her youngest stepdaughter on February 3, with the caption: "So proud of the woman you're becoming. Thank you for allowing me into your world. Happy Birthday @buuski #proudstepmom"
