Justin Timberlake cancelled his sold-out concert in New York City on Wednesday night (19.02.14).
The 'Mirrors' hitmaker was forced to pull the plug on his scheduled show at Madison Square Garden, as part of his 20/20 Experience World Tour, at the eleventh hour after coming down with a mystery illness.
Hours before the gig was due to take place, the 33-year-old star announced he wouldn't be performing on Twitter, tweeting: "Hey NY. There is never an easy way to do this... Unfortunately, I have to postpone tonight's show to Friday due to health reasons."
He added: "I am truly sorry to everyone that have tickets for tonight. It kills me to have to do this. I hope to see you all on Friday. JT"
Justin has rescheduled his cancelled concert for Friday (21.02.14), following his second sold-out gig at the venue on Thursday night (20.02.14).
He will also appear on 'The Tonight Show Starring Jimmy Fallon' on Friday before moving on to perform in Buffalo, New York on Saturday (22.02.14).
The singer gave no indication he was feeling unwell when he took to the stage in Chicago on Tuesday night (18.02.14).
Justin, who is married to 'Total Recall' actress Jessica Biel, kicked off his current tour last November and is due to finish it in Poland in August.

Adam Brody has confirmed he and Leighton Meester are married.
The 34-year-old actor, who got engaged to the former 'Gossip Girl' beauty in November, secretly tied the knot with the 27-year-old actress by the ocean in Northern California recently.
Asked whether reports of their nuptials were true, the former 'The O.C.' star told TooFab.com: "Yeah. Thank you."
Adam also gave photographers a thumbs-up when asked how his new wife was doing.
Meanwhile, a source close to the couple told E! News that they were desperate to keep their wedding very private and tied the knot "a couple of weeks ago."
The insider said: "Leighton and Adam got married in Northern California by the ocean a couple of weeks ago. It was a very small and intimate wedding with close family and friends. It was beautiful."
The couple were spotted on honeymoon at the St. Regis Resort Punta Mita Resort in Mexico last weekend, where they also celebrated Valentine's Day together on Friday (14.02.14).
Adam and Leighton only started dating last year but first met when they co-starred in romantic-comedy 'The Oranges' in 2011.
Adam was previously romantically linked to Rachel Bilson and 34-year-old director Lorene Scafaria - who helmed Steve Carell and Keira Knightley's comedy drama movie 'Seeking a Friend for the End of the World' - while Leighton has previously dated 'Austin Powers' actor Aaron Himelstein.

Bastille have joked they're ready to "retire and work in McDonalds".
The 'Pompeii' hitmakers admit they're so happy to be honoured with the Best British Breakthrough prize at the BRIT Awards, held at London's O2 Arena, tonight (19.02.14) that they could now just give up their careers to work in a fast food restaurant.
Speaking exclusively to BANG Showbiz, frontman Dan Smith joked: "It's completely unexpected to win Best British Breakthrough. We can now give up music, retire and all go and work in McDonalds like we always dreamed."
The quartet - consisting of Dan, Chris Woody, Kyle Simmons and Will Farquarson - fought off stiff competition from the likes of London Grammar, Disclosure, Laura Mvula and Tom Odell for the prize.
However, the band - who released their debut album 'Bad Blood' in March 2013 - admit they never expected to achieve so much success in just a year and they're really grateful for being able to travel the world and meet their fans.
Dan explained: "It's been a wicked year, it's a year no-one, apart from a couple of people, could have predicted. We've been able to go all over the world, it's been ridiculous."
Bastille had also been nominated for Best British Group, Best British Single for their track 'Pompeii' and Best British Album, but narrowly missed out on the gongs.

Harry Styles almost missed One Direction receiving a BRIT Award.
The 'Little Things' hitmakers were honoured with the Global Success prize tonight (19.02.14), but the 19-year-old hunk left his bandmates hanging on-stage while he dashed off to the toilet.
Liam Payne, Niall Horan, Zayn Malik and Louis Tomlinson were forced to stall time as they waited for the heartthrob to join them.
Quick-thinking Liam, 20, asked the crowd: "Has anyone seen the curly lad? Right, there's four of us now."
He added: "I want to say thank you to our international team, management, the fans."
Then Harry sprinted on stage, snatched the microphone, and said: "I'm really sorry I was having a wee, the toilets are ages away!"
He then whispered to Liam, "what did we win?"
Before adding quickly: "A massive thank you to all our incredible fans. Thank you."
The boyband - who narrowly missed out on British Group and British Single trophies - were presented the award by Rosie Huntington-Whiteley at the glamorous event, held at London's O2 Arena.
Speaking exclusively to BANG Showbiz, Liam said: "It's absolutely amazing to win the award, I can't believe we're here again, third time we've been to the BRITs now, our fourth award, it's absolutely incredible. Getting nominated for the first award was amazing, now we're receiving a Global Success Award."
Niall then did an impromptu rap about winning the gongs as Liam became a human beat-box.

The Arctic Monkeys triumphed at the BRIT Awards 2014 after winning two awards.
The band - consisting of Alex Turner, Jamie Cook, Matt Helders and Nick O'Malley - scooped the Best British Group prize and British Album of the Year for their LP 'AM' at the glamorous event, held at London's O2 Arena tonight (19.02.14).
After accepting the award for Best Group - which was presented by Lily Allen - Alex said: "That 15 quid we put on One Direction has gone down the drain. There's a lot of people we need to thank, but they need to hear their names read out as much as you need to hear of people you don't know."
The group fought off stiff competition from the likes of Bastille, Disclosure, One Direction and Rudimental for the gong.
Picking up Best Album later in the night, which saw them become the first band to do the double - win Best British album and Best British group - three times, Alex added: "That rock'n'roll, it looks like it's fading away, but it'll never die."
Meanwhile, David Bowie also won big after securing the Best Male Solo Artist accolade, 30 years on from his first win in 1984, after beating the likes of Jake Bugg, James Blake, John Newman and Tom Odell.
The 67-year-old singer, who is the oldest recipient of an award in the BRITs history - was unable to attend the gala and chose Kate Moss to collect his prize for him.
Ellie Goulding kicked off the night's events after being crowned the Best British Female Artist, before taking to the stage to give an energetic performance of her hit 'Burn'.

Bette Midler is set to perform at the Oscars next month.
The 'Wind Beneath My Wings' hitmaker will take to the stage to sing at the awards show in the Dolby Theatre in Los Angeles for the first time on March 2.
It is not yet known what song the 68-year-old star, who was nominated twice for Best Actress in the past, will perform at the star-studded ceremony.
But Bette, who has served as a presenter several times in the past, hinted she hasn't decided yet, as she wrote on Twitter on Wednesday (19.02.14): "Now that the news is out, what shall I sing at this years #Oscars? (sic)"
Oscar producers Neil Meron and Craig Zadan also convinced Barbra Streisand to sing 'The Way We Were' during a tribute to its late composer, Marvin Hamlisch, last year.
In a statement, they said: "We are thrilled to have Bette perform on the Oscars for the very first time. We believe she will make our Oscar telecast an especially moving evening."
U2 and Pharrell Williams are among the other artists to have agreed to sing at the prestigious event this year.
The Irish rockers will perform their track 'Ordinary Love,' which is nominated for best Original Song, while Pharrell will sing his nominated hit 'Happy' from the film 'Despicable Me 2.'
'Frozen' star Idina Menzel will sing 'Let It Go' from the film and Karen O will sing 'The Moon Song' from the movie 'Her', which are also both nominated in the category.

Julia Roberts' mother is reportedly battling lung cancer.
The 'August: Osage County' star - whose half-sister Nancy Motes overdosed and died on February 9, after writing a "ranting" note that allegedly claimed the actress "drove her" to suicide - has "suffered an emotional collapse" following Nancy's death, as she has been secretly caring for Betty Lou Motes at her home in Malibu, California since doctors found a cancerous tumour on her lung during a routine MRI scan in November.
A source told the National Enquirer magazine: "She was already reeling from her mom's cancer crisis. Now, she's been deeply hurt and stung by all the criticism after Nancy's death and feels she doesn't deserve it. Julia insists that Nancy's death was not a suicide."
The insider added that the 46-year-old Oscar-nominated actress "wants to believe that the overdose was accidental, that somehow Nancy expected to be discovered just before she passed away. Julia's been crying her eyes out ever since."
Julia moved Betty, who had a heart attack and angioplasty in 2009, into her home late last year to look after her when she was diagnosed.
The source added: "Everyone was frantic because Betty has a history of smoking and emphysema."

Julianne Hough's new boyfriend feels like "a pretty lucky guy."
The 'Safe Haven' actress, who split from Ryan Seacrest last March after three years together, recently started dating Canadian ice-hockey star Brooks Laich after they were introduced by their mutual friend, actor Teddy Sears, in December, and he admits he is completely smitten with the blonde beauty.
The 30-year-old athlete told Washington D.C. radio station 106.7 The Fan on Wednesday (19.02.14) that Teddy, who worked with Julianne on her upcoming film 'Curve' thought they would be the perfect match.
He said: "On set, apparently, he (Teddy) was talking with Julianne, and said he had recently just got married--just got back from his honeymoon--and then asked her if she'd been seeing anyone, and she said no or whatever, and I guess he was watching our hockey game at the time. He always watches the game on Game Center on his iPad. I guess he just showed her the iPad and said, 'Well I've got a guy for you,' or something. I guess that was sort of how it started."
Brooks finally met Julianne a few months later.
He said: "He kept mentioning her name and mentioning her name, eventually we connected. Happy we did. In December, Teddy and Melissa [Teddy Sears' wife] came back for a little wedding reception of theirs, back in D.C. here, and Jules came out with them and I got to meet her at that point."
Asked about their romance, he added: "I don't want to get into a whole lot of it; I'm kind of shy on my personal life. But she's a cool, cool gal. She's just a sweetheart, very loving, very giving. She puts so much great out into the world. I'm a pretty lucky guy."
Meanwhile, a source close to the former 'Dancing with the Stars' professional, 25, told E! News that she is equally taken with her new boyfriend.
The insider said: "He's a very nice guy. She really likes him."

Taylor Swift sent an Olympian a personal good luck message.
The '22' hitmaker reached out to American freestyle skier Torin Yater-Wallace to wish him well at the Winter games in Sochi, Russia, after he named her as his celebrity crush and revealed he listens to her music during his training sessions.
In a new video for 'Entertainment Tonight,' the 23-year-old star said: "Hey, it's Taylor! I just wanted to say good luck to everybody going to Sochi. I wanted to wish all the winter athletes good luck, and Torin -- thanks for listening to my music while you practice. That's amazing."
After seeing the video, the 18-year-old Olympian said: "Whoa. She said my name."
Asked what kind of date he would take the country singer on if he ever got the chance, according to UsMagazine.com Torin replied: "We'd go to the Hickory House in Aspen and get some barbecue ribs and maybe go hot tubbing at the Ritz Carlton. And then she can come over and we can see what happens after that."
Last week Taylor received a sweet Valentine's message from American freestyle skiing slopestyle bronze medallist Nick Goepper, who posed with his medal and a whiteboard with a heart and the message: "Taylor Swift, will you be my Valentine?"
The 'Red' singer, who previously dated John Mayer, Taylor Lautner, Jake Gyllenhaal and Conor Kennedy, did not respond publicly as she spent the romantic day on Friday (14.02.14) in the studio recording.
She posted a picture of her with producers Karl Johan Schuster and Max Martin, which shows them celebrating with glasses of champagne, with the caption: "It was a studio Valentines Day with Max and Johan!"

Miley Cyrus is reportedly "hooking up" with Jared Leto.
The 'Wrecking Ball' hitmaker, who split from her 'The Hunger Games' star fiance Liam Hemsworth last September, spent time with 'The Dallas Buyers Club' star at his home in Los Angeles earlier this month.
A source told Us Weekly magazine: "(They) are hooking up. She stayed over at his house in L.A. in early February."
Another source said that the 42-year-old Oscar-nominee, who previously dated Cameron Diaz and Ashley Olsen, and the 21-year-old singer have "known each other for a while."
The 30 Seconds to Mars frontman was photographed catching up with Miley at Clive Davis' pre-Grammy Awards party late last month and they have developed a close bond.
An insider said: "They like to have a good time, they love to talk about art and music -- and they're both comfortable with nudity!"
But a friend close to Jared insisted his romance with Miley, who kicked off the US leg of her 'Bangerz' world tour last weekend, isn't serious, explaining: "Jared doesn't do girlfriends."
The actor recently sparked rumours he was dating '12 Years a Slave' star Lupita Nyong'o after they were seen getting cosy at the Crosby Street Hotel in New York City last week.
An eyewitness previously said: "They were huddled at a corner table together looking very close."

Philip Seymour Hoffman left his $35 million fortune to Mimi O'Donnell.
The 'Capote' star, who was found dead in his apartment in New York City on February 2 from an apparent heroin overdose, named his estranged partner and the mother of his three children, Cooper, 10, Tallulah, seven, and five-year-old Willa, as the sole beneficiary of his estate.
A source told gossip website TMZ.com that the Oscar-winning actor wrote his will in 2004 before the birth of his daughters, and he also expressed a desire for his son to be raised in Manhattan so he could be exposed to the city's culture, arts and architecture.
The 46-year-old star also named Chicago and San Francisco as back-up places for Cooper to grow-up if his original request was impossible, and asked that his son visit both cities at least twice a year for cultural purposes.
'The Hunger Games' actor reportedly fell off the wagon in 2012 after being sober for more than 20 years and he entered rehab in May 2013.
Philip was allegedly found with around 70 bags of heroin inside his apartment after Mimi, who had recently kicked him out of their home in an act of "tough love," sent his friend David Bar Katz over to check on him when he failed to show up to spend time with their children.
Some 400 mourners, including Cate Blanchett, Julianne Moore and Diane Keaton, attended Philip's private funeral at St. Ignatius Loyola Catholic Church in Manhattan earlier this month.
