Amanda Seyfried boarded a plane with a knife in her pocket.
The 'Lovelace' actress took to Twitter to confess that she had boarded a flight on Friday (14.03.14) with a Swiss army knife in her pocket but wasn't aware that she had been in possession of the dangerous object until she had already been seated on the plane.
She wrote on Twitter: "Dear TSA: This Swiss Army knife wasn't detected through security and I unknowingly carried it on board. Scary! (sic)"
In March of last year, Transport Security Administration announced retractable knives containing blades shorter then 2.4 inches and narrower than 5 inches at the widest point, would allowed on board in passengers hand luggage, with the restrictions to be lifted the following month.
However, by June, TSA announced it had abandoned the plan in the face of fierce congressional and industry opposition.
Meanwhile, Amanda has credited her boyfriend Justin Long for helping to boost her confidence.
She began dating the 'He's Just Not That Into You' actor, 35, last summer and admitted she "can do no wrong" in his eyes.
Amanda told the February issue of US InStyle magazine: "You've got to find someone who makes you feel like you could gain 20 pounds and he'd still look at you the same. But as an actress it's easy to feel insecure."

Josh Brolin has admitted to experimenting with heroin.
The 'Men In Black 3' actor has opened up on his past struggles with the "horrible" class A drug admitting that while he never became addicted to the substance, he has 19 friends who have all died after overdosing on the drug.
Josh told The Guardian newspaper: "I tried heroin. That sounds so horrible when you put it like that. But yeah, I tried heroin.
"I mean, I never got into it and I never died from it, which is a good thing, but I've had 19 friends who died. Most of those guys I grew up with, they're all dead now."
The 46-year-old actor admits he used to be open to experimenting with different drugs, in a bid to live life to the fullest, however he now regrets putting his life in danger.
Josh explained: "I used to think you should try to deconstruct everything. Experience everything. Just get yourself out there. But I don't believe that any more. Having adventures is all very well, but an imagination can make up for all that. That's the more intelligent way to be. And it keeps you out of harm's way."
Brolin also opened up about being arrested for public intoxication on New Year's Day 2013 and the subsequent break-up of his marriage with Diane Lane.
He mused: "It was another turning point.But I realized that I was on a destructive path. I knew that I had to change and mature."

Joey Essex wants to compete on 'Strictly Come Dancing'.
The reality TV star has admitted he would love to appear on the next series of the celebrity ballroom contest, and he thinks he could "easily pull off one of their outfits".
He told The Sun newspaper: "I love to dance but I want to do more cool dancing. Maybe I should go on it and mix it up and do a bit of break-dancing.
"I've never watched it that much, but I've seen it. I think I could easily pull off one of their outfits.
"They're the ones with the diamonds, aren't they? I'd look sick in that."
The 23-year-old star - who was mocked for several dimwitted moments during his time on 'I'm a Celebrity... Get Me Out of Here!' - has revealed he still wants to go back to school because he "didn't really learn much last time".
He said: "I still think I'd fail my GCSEs. I don't know anything. I'd probably learn less."
However, he recently admitted he was too busy for love because of his new show 'Educating Joey Essex'.
He told BANG Showbiz: "I mean, I'm single but I have just been concentrating on the show, really. I'm too busy [for girls] at the moment. Every single day I'm getting up at early hours of the morning doing different things."

'The Voice' judge Ricky Wilson will have his raunchy dancing cut from tonight's show (15.03.14).
A section of the programme - in which the Kaiser Chiefs singer thrusts his groin at fellow judge Kylie Minogue - has been cut from the upcoming broadcast because it was deemed too racy for the family show.
He was said to be gyrating with his hips to put the 'I Should Be So Lucky' hitmaker off as she gave an interview, he said: "I'll give you a treat.
"I have to give you a treat every now and again. I wouldn't mind a return of the favour any time."
However, according to reports in The Sun newspaper the stunt was "too sexual" for the programme's family audience.
An insider revealed: "He's obviously miming having sex, so producers decided to err on the side of caution and bin it.
"It was was a bit of banter but some people might take it the wrong way."
Although Kylie has been a huge boost for the show in its third series, the judge recently admitted she wasn't sure if she'll be returning for a second year.
She said: "I'm already doing it again in Australia, but UK or Australia, I don't know if I could [do another season] because I'm going to be touring. We'll see.
"I am doing 'The Voice' Australia so that will carry on until July. I've got to get through at least this one first, and then two with Australia."

Debbie Harry would like to see a Blondie biopic made.
The 'Heart of Glass' singer thinks a film about her group could help people be better "informed" about their career, and the New York music scene they emerged from in the 1970s.
Asked if she would like to see a Blondie biopic, she said: "It's difficult. You can only really skim the surface. If it's good entertainment, honest, well-acted and directed? Maybe.
"I think many people could be informed and have a finer appreciation of the person or era."
However, the 68-year-old star admits she has little written down in physical format that could help inform such a project.
Asked if she had kept diaries, she replied: "Unfortunately not. I wish that I had. My impressions will simply be that, impressions. It's funny, someone will say something and then a memory will come flashing back of some big event. But I'm noteless. I guess I'm lazy. Well, I'm not so much a person who deals with facts as much as feelings."
However, Debbie - who, along with the rest of Blondie, recently picked up the Godlike Genius prize at the NME Awards - prefers to look forward, not back.
She added in an interview with Stylist magazine: "Doing interviews, getting the award forces you to deal with your history so to speak - it might give me some kind of way of dealing with the present.
"But I like moving ahead. I like change, I like new things. It's good to escape. I have an adventurous spirit."

Justin Bieber could be forced to talk about Selena Gomez in court.
The troubled singer was asked about his on/off girlfriend during his deposition last week - part of the ongoing lawsuit after his bodyguard allegedly beat up a photographer - and refused to answer questions, but now the lawyer has insisted he has a right to know whether they are currently dating.
According to gossip website TMZ, the 'Beauty and a Beat' hitmaker may have to open up about their rumoured reconciliation after court documents were filed.
The lawyer - representing the photographer - has claimed Justin and Selena's relationship is relevant to the case because she was with him at the scene of another apparent attack on a paparazzo in 2012.
It is said if Justin and Selena are back together, she could be considered a biased witness and not credible.
He responded: "Don't ask me about her! Do not ask me about her!"
In addition to forcing Justin to answer questions about the 'Spring Breakers' actress, the lawyer also wants him to be punished for his rude behaviour before he walked out of court during the deposition.

Miley Cyrus has a tattoo of a cat on the inside of her lip.
The 'Wrecking Ball' singer has unveiled the new design, which shows a yellow cat crying a single blue tear, and adding to her already huge collection of body ink.
Along with a picture on Instagram, she wrote: "Sad Kitty."
The tattoo can only be seen when Miley pulls down her bottom lip to reveal the cat, her latest in a string of designs covering her body.
As well as a portrait of her grandmother, the 23-year-old star also has a dream catcher, a quote by Theodore Roosevelt, a skull, the word 'Karma' and a mini replica of da Vinci's anatomical heart drawing.
Miley recently caused controversy at a concert in Milwaukee, Wisconsin when she had to perform her track '23' wearing only her underwear.
She later explained on Twitter: "not a new outfit for 23 I didn't make my quick change and I couldn't not come out for the song so I just had to run out in my undies 🙁
"Never happened to me before. But I love my fans as much as they love me! I couldn't miss 23
"Show must go on 🙁 (sic)"

Shakira has hit out at critics of her sexually charged music videos.
The singer has come under fire after the raunchy promo clip for 'Can't Remember To Forget You' - her duet with Rihanna - but she has argued she is not allowing herself to be "objectified".
She told The Independent newspaper: "You see baseball players grabbing each other's asses, and nobody says anything! I don't think that I put myself in any situation in which I am objectified.
"But I do take advantage of, you know, feeling sensual and feeling sexy.
"And I think that is tremendously empowering and is not diminishing in any way. I feel that any woman who is in control, who is in touch with her femininity and sensuality, is a woman that is empowered."
The 'Hips Don't Lie' hitmaker recently admitted that her husband Gerard Pique has banned her from making music videos with other men.
She said: "He's very territorial, and since he no longer lets me do videos with men, well, I have to do them with women.
"It's more than implied in our relationship that I can't do videos like I used to. It's out of the question - which I like, by the way.
"I like that he protects his turf and he values me, in a way that the only person he would ever let graze my thigh would be Rihanna."

Louis Walsh is in the middle of a 'Britain's Got Talent' fix row after accusations his boy band were "fast-tracked" into the second round.
The music manager and talent show judge's newest group Hometown are said to have been given an easy pass by the panel, with Simon Cowell reportedly doing his colleague a favour by giving the quintet some exposure.
An insider told The Sun newspaper: "It seems like yet another talent show fix."
A music industry executive added: "It looks like fast-tracking. They weren't even that good.
"Louis needs a big favour from Simon to help get them off the ground - and he got one."
After their performance, the 54-year-old star was impressed but joked he was disappointed by the prospect of working with Louis.
He told them: "I don't know what's more annoying - the fact you were good o the fact I might have to work with Louis Walsh again."
However, a spokesperson for the show has insisted the group received "no special treatment", noting that Simon, 54, had no idea Louis was managing the group until after their performance.
They said: "Simon had never met the band and did not know who their manager was until they revealed it on stage after their audition. They got no special treatment."

Stephen Mulhern gets mistaken for Ant McPartlin.
The 'Britain's Got Talent' host has admitted some fans get him confused with the show's co-presenter, and joked he is "riding it out" to reap the benefits of the mix-up.
He told The Sun newspaper's TV Magazine: "I always get asked: 'Are you Ant?' I'm riding it out.
"In a hotel the other day, I had forgotten my phone charger. A woman on reception got excited thinking I was Ant and lent me hers. I told Ant - now he thinks I go around pretending to be him."
However, Stephen has joked while Ant and his professional partner Dec Donnelly are two of his only celebrity friends, he wouldn't trust them to give good advice.
He revealed: "Ant and Dec, Emma Willis and Holly Willoughby are proper mates. But that's about it.
"If I had a problem I'd go to Holly, and if I want advice that makes no sense and probably makes things worse, I'll ask Ant and Dec."
He did put his faith in the TV duo to "make it over in the US", and admitted he'd love to visit them if they succeeded.
He said: "I think Ant and Dec will make it over in the US, they work so hard.
"I'll pack their bags if they want. Los Angeles is a lovely place for a holiday. They can put me up in their mansion."

Britney Spears suffered a "panic attack" at an Oscars party.
The 'Perfume' singer, who had a public breakdown in 2007, reportedly felt overwhelmed at Sir Elton John's AIDS Foundation Oscar-viewing party at West Hollywood Park, and made a quick dash to the exit after just minutes of being in the room.
A source said: "Britney was excited when she first went to the party but moments later she was fazed about being at such an over-crowded event.
"She started to break out in a sweat and become short of breath, it was like she was having a panic attack."
The 32-year-old star shaved her head during a meltdown seven years ago and was photographed attacking a paparrazo's car with an umbrella.
Her breakdown led to her losing custody of her sons Sean Preston, eight, and Jayden James, seven, to ex-husband Kevin Federline, and the singer, who suffers from bipolar disorder, still has issues being at parties.
The source added to Closer magazine: "Britney still finds large crowds nerve-wracking and doesn't feel comfortable at showbiz events.
"The chaos of the red carpet and all the unfamiliar faces is very daunting. She manages to block out the crowd and put on an act when she's on stage, but it's harder when she's socialising."

Michael Jackson has been accused of beating up his chimp Bubbles.
The late singer's pet was reportedly "being beaten" while in his car, and a leading chimpanzee expert insisted she tried to intervene when she'd heard about the way he was being treated.
Jane Goodall told TMZ: "I went to see him and we talked about Bubbles. I ticked him off.
"Bubbles is still alive and he's beautiful, but when he was with Michael he was being beaten ... Chimpanzees belong in the forest. By the time they are seven or eight they are dangerous."
While Jane didn't directly name the 'Thriller' hitmaker - who passed away in 2009 - as the abuser, the ex-husband of the star's sister LaToya has claimed he saw the beatings first-hand.
Jack Gordon said: "I saw Michael punch Bubbles in the face, kick him in the stomach."
The gossip website notes that sources from the singer's camp have denied the claims, conceding there have been reports over the years of the chimp being treated like a king.
Bubbles, 33, now lives in an animal sanctuary in Florida.
