Taylor Swift is being sued by clothing brand Lucky 13.
The 'Love Story' singer counts 13 as her favourite number and sells T-shirts with 'Lucky 13' written on them through her online store, but Robert Kloetzly who owns Lucky 13 clothing - which has been trading since 1991 - feels she is stealing his business.
In a lawsuit lodged today (20.05.14), Robert accuses the singer of trademark infringement for unauthorised use of Lucky 13's branding, and claims they have contacted her people numerous times with no resolution.
In court documents seen by website TMZ, Robert describes Taylor as a singer who likes "fast cars and dangerous men who drive them inappropriately," which is the same demographic as his company targets. It also cites the star's music video for 'I Knew You Were Trouble' because it "depicts stylish, attractive, tattooed individuals in provocative situations," much like Lucky 13's branding.
Robert is seeking to get Taylor's merchandising site shut down and all of the profits she's made so far given to him, or damages paid to his company, whichever is greater.
Taylor, 24, was born on December 13, has the twitter name TaylorSwift13 and can often be seen with the number penned on her hand.
Explaining her attraction to that particular number, she has previously said: "The significance of the number 13 on my hand ... I paint this on my hand before every show because 13 is my lucky number - for a lot of reasons.
"I was born on the 13th. I turned 13 on Friday the 13th. My first album went gold in 13 weeks. My first number one song had a 13-second intro. Every time I've won an award I've been seated in either the 13th seat, the 13th row, the 13th section or row M, which is the 13th letter. Basically whenever a 13 comes up in my life, it's a good thing."

Roy Orbison's sons have used new technology to record a song by their late father.
The 'Oh, Pretty Woman' hitmaker, who died in 1988, recorded a track called 'The Way is Love' on a boombox and his sons Alex, Roy Jr and Wesley have been able to work on the song together, which will now feature on a 25th anniversary re-issue of Roy's last album 'Mystery Girl' from 1989.
Alex told BANG Showbiz: "My mom felt very strongly about the song and she tried to do something with it forever.
"We found the [original] tape in a giant pile we were going through and it's such a beautiful song with a strong message.
"It really did feel like we were recording with my dad, which I never got to do before he died. We made sure everything was perfect and layered all of the tracks.
"Looking at the finished product, I think he'd definitely be proud of what we've done."
Alex, who thinks there could be more tracks they want to work on in the future, claims being in the studio with his brothers brought them closer together.
He said: "My dad had brothers himself and he had said, 'Sometimes you don't get along but at the end of the day you have to hug and love each other'. We came together as brothers over this."
A documentary entitled 'Mystery Girl: Unraveled', executive produced by Alex, Roy and Wesley and directed by Alex, also features new interviews with Billy Burnette, John Carter Cash, Mike Campbell, Steve Cropper and more, along with never-before-seen interviews with Bono and the late Barbara Orbison.
Alex said: "We feel like one of the goals of the documentary was to show the recording process was like but also what my dad was like.
"You get to see a bit of his personality and his sense of humour. His laugh and things that are so endearing to us. We had great archive footage and it was a goal for us to show the man behind the sunglasses.
"He had such a dark ominous look at times, the songs were so heart-breaking and people assumed he was somber and morose, but he was such an upbeat, kind and gentle soul."
Roy Orbison's re-release of 'Mystery Girl' is out now.

Alessandra Ambrosio wants her daughter to be "nice and disciplined".
The Victoria's Secret beauty would like five-year-old Anja - her eldest child with fiance Jamie Mazur - to grow up feeling confident about herself and to know appearance isn't the only thing that matters.
Alessandra - who also has two-year-old son Noah with Jamie -said: "Having a perfect body isn't everything. I want my daughter to be nice, have a good education and be disciplined. That's what makes people like her. A perfect butt doesn't make an amazing person. It's about feeling confident."
Despite her slender figure, Alessandra admitted she never exercised until after her daughter was born.
She said: "When I started with Victoria's Secret at 21, I never worked out. Then when I got pregnant with my daughter, I gained about 60 pounds and had to walk the Victoria's Secret show three months later.
"That was the first time I had to really fight to get my body back into shape."
And while the brunette beauty now works hard on her figure, she admits she doesn't "do much" for her arms as she doesn't think people notice them as much as the rest of her.
Speaking to Self magazine, she said: "When you're in a bikini, your abs are the most important.
"I like doing bridges, and I'll also finish a workout with 100 bicycle crunches.
"I'll do three sets of 25 Supermans [to tone my back]. I don't really do much for my arms; throwing my kids in the air helps already. Plus, as a Brazilian, I know the last thing a man is going to look at -- even after your feet - is your arms!"

Halle Berry thinks she got pregnant because of her daughter's prayers.
The 47-year-old actress - who has daughter Nahla, six, with former boyfriend Gabriel Aubry and seven-month-old son Maceo with husband Olivier Martinez - thinks it is a miracle she had a second child because she was "premenopausal" shortly before she learned she was expecting another baby.
She said: 'I mean, I didn't think it was possible to have another baby and I thought for sure I had a need never to get married again. So, I've learned never to say never.
"Nahla prayed and prayed for him for like a year and a half for a baby and a bunk bed and she got both of those things.
"Only her prayers could have done this I didn't think it was possible at my age, honestly. They call it a geriatric pregnancy."
"I was, you know, on my way. This is probably way TMI, but I was kinda premenopausal, so to have this happen was huge."
The 'X-Men: Days of Future Past' star says her daughter dotes on her little brother, and loves nothing better than changing his outfits.
She told talk show host Ellen DeGeneres: "He's like one of her dollies that came to life.
"You know and all she wants to do is change his clothes. Like she'll purposely like throw something on his shirt and say, 'Oh mommy, he's got to change his shirt. He has a mess on him!' She just likes to change his clothes, change his diapers..."

Courtney Love tried to "help and mentor" Peaches Geldof.
The Hole rocker - who has battled drug addiction several times - was horrified when the tragic socialite, whose death last month has been linked to heroin use, visited her in Los Angeles at the Chateau Marmont, bringing with her a friend who was carrying a number of prescription drugs.
While Courtney admitted to "pushing" Peaches - whose mother Paula Yates died of a heroin overdose in 2000 - out of the room because she was so tempted by the drugs, their encounter made her vow to want to try and help her however she could.
She said: "My drug was heroin, I stopped taking it in the 90s, but I have taken the pills, the Roxycontin, Oxycontin.
"Peaches was in a room with a friend who had a bag full of these drugs, like 500 pills and I wanted it so badly, never have I ever wanted anything more - no man, no money - and I had to physically push Peaches and her friend out of the door.
"I was shaking and I kept thinking of the way her mother died and I thought I owe it to this girl to be an example.
"I was trying to help her, but at that point in her life, it proved to be impossible. Now the parallels to her mommy are horrific. It terrifies me for my own child."
Courtney - who has 21-year-old daughter Frances Bean with late husband Kurt Cobain - admitted she wasn't "shocked" to learn of Peaches' death.
She added in an interview with Grazia magazine: "You just can't believe it happened, it's so f***ing tragic. This girl was vivacious, so full of life and it was weird and horrible that she has passed away.
"I read heroin was involved and I was not shocked. I know how Peaches liked opiates."

James McAvoy almost crashed a helicopter on his way to Sao Paulo.
The 'X-Men Days of Future Past' actor was travelling to the Brazilian city, where he was promoting the film, when the pilot invited him to take control of the aircraft and hold the joystick, but things wen't wrong.
Talking on 'The Daily Show' James recalled the experience, he said: "I looked at him and thought he was joking. And then he took his hands off the joystick..."
Show host Jon Stewart joked: "Are they difficult to fly, were you thinking this pilot is insane?"
James added: "I did think the pilot was insane but I like that kind of crazy. So I was holding the joystick and was thinking this is doable, this was fine and then the slightest movement and then it would go shwwm......I think the pilot s**t himself and took back the controls. "
As the 35-year-old star was flying out of the city, he found he was travelling with the same pilot and the "brave" man let him take control again.
He added: "But two days later flying out of Sao Paulo, we had the same helicopter pilot, he's a very brave man, he let me do it again!"
'The Daily Show' airs tonight at 11pm on Comedy Central Extra.

Prince Harry's impersonator has been wished luck on his new reality show by a Prince William lookalike.
Matt Hicks - who duped 12 American females into thinking he was the flame-haired royal for new dating reality show 'I Wanna Marry Harry' - has befriended Simon Watkinson, who claims to be the world's best Prince William impersonator, on Twitter.
The royal double took to the social media site to wish Matt luck on the launch of his show, which begins airing on US network FOX tonight (20.05.14).
He wrote: "Good luck mate!"
Prince Harry's doppelgänger responded: "Thaaaaaanks. Think I need it! (sic)"
And it seems the royal impostors could be planning a public meet-up, which is certain confuse fans of the real Harry, 29, and William, 31.
Simon - who tweets using the handle @WillsLookalike - wrote to Matt: "I'm sure it will be brilliant. Such a good laugh. I'd like to hear more about it all once it's all calmed down for you. (sic)"
The professional Prince William impersonator has appeared on TV shows across the world and taken part in numerous photoshoots posing as the royal heir.

Alex Turner thinks Metallica headlining Glastonbury "doesn't add up".
The Arctic Monkeys frontman, who has been top of the bill twice with his band mates Matt Helders, Jamie Cook and Nick O'Malley, aren't impressed by the news that the heavy metal band will headline the Sunday this year.
Alex said: "I heard all the rumours [that they would play]. I'm not sure it adds up. I know we'd buzz off it, but fundamentally could you have Metallica in the hippy nucleus?"
The first time the band played the event at Worthy Farm they hung out with Lily Allen but still got stuck in to enjoying the festival atmosphere.
He said: "The first time we went to Glastonbury was when we played it. I did the Stone Circle thing. I was dressed as a crocodile, because Lily Allen had a load of fancy dress costumes. I remember wrestling James from Klaxons in the mud as the sun rose."
The 28-year-old star, who hails from Yorkshire, claims his best piece of advice for anyone wanting to get the most out of a festival is to join a band and play themselves.
He added to Time Out magazine: "I went to Leeds festival twice when I was about 16 and 17. The following year we were playing in a tent there - much better! We never really considered going to any festivals down south. It just seemed too far away."

Katherine Parkinson has hinted 'The IT Crowd' might be made into a movie.
The actress suggested Channel 4 bosses are considering bringing the popular sitcom about a gang of geeky office workers to life on the big screen.
Viewers were left disappointed when the show wrapped last September after a successful seven-year run, and Katherine revealed the show could possibly be revived in a feature-length format with a musical twist.
According to the Radio Times, she teased: "I think if it did have a future, it would be that sort of thing. I always thought it would be nice to do a sort of musical film!"
Katherine bagged the gong for Best Female Performance In A Comedy Programme at the BAFTAs over the weekend, while her co-star Richard Ayoade scooped the Best Male Performance prize.
The star was quick to backtrack about the movie for fear of getting in trouble with show bosses, however.
She joked: "You'd have to ask [show writer] Graham Linehan."
Katherine also said filming the last ever episode of 'The IT Crowd' - which also starred Chris O'Dowd and Matt Berry - was very emotional.
She recalled: "I did feel a bit emotional. I feel like I've grown up on that show. The relationships I have with them are all so deep rooted, really."

The stars of 'Sherlock' have made "progress" on shooting the next series.
Writer and star Mark Gatiss - who plays Mycroft Holmes on the show - has hinted the fourth series of the hit detective drama could begin production in the near future as the show's busy cast and crew, including Benedict Cumberbatch, have finally found dates they are available.
Speaking to Radio Times, he said: "I can officially tell you that we are moving closer to agreeing some dates to shoot. If that sounds like a party line, it is.
"That is proper progress because Ben and Martin [Freeman] are so busy, and Steven and myself are so busy, but actually trying to get everybody to interlock ... we have made significant progress."
Mark, 47, also denied speculation a fourth series could be shelved in favour of doing a one-off 'Sherlock' film, insisting three 90-minute episodes is still "the plan".
He added to Digital Spy: "There was talk amongst people who have nothing to do with 'Sherlock', I'm afraid."
Mark previously claimed shooting of the fourth series depends on Martin and Benedict's schedules as they have become "superstars" with numerous film and TV roles following the success of the BBC One drama.
He said: "There was suddenly a kind of outraged response that it might not be back until 2016 but that's precisely how long it always is. It's always two years! But we'd like to return soon, of course."

EastEnders' Tina Carter and Tosh are to have a baby.
The soap's lesbian couple will be at the centre of a new baby plot as they try to start a family following their recent decision to move in together.
Tina - played by Luisa Bradshaw-White - has been seen getting close to returning Walford character Sonia Fowler (Natalie Cassidy) in recent weeks, even sharing a steamy kiss with her, but the café worker will soon be determined to settle down with Tosh (Rebecca Scroggs).
Quizzed if Tina and Sonia will pursue a relationship, Luisa told ITV's 'This Morning' earlier today (20.05.14): "No, not this year. I've heard rumours, but I've got my girlfriend and we're going to have a baby. Well, we're going to try!"
The 38-year-old actress also admitted she worried about joining such an intense TV show but was pleasantly surprised by how easily she settled into her role as Tina after joining the soap last year.
Luisa said: "I did 'Grange Hill' for four years, and 'Holby City' for four years at the same studio. I always would say, 'I can't do 'EastEnders' - too many cameras, too quick, too many episodes, too famous.' Then I became a mum and I really chilled out. I got older and it's the easiest job I've done."
Meanwhile, co-star Declan Bennett - who plays the mysterious Charlie Cotton - defended his shady character, whose identity was recently questioned by his grandmother Dot Branning (June Brown) after only discovering his existence earlier this year.
The actor said: "I think there's some stuff going on in Charlie's world. He's getting himself mixed up in a lot of things. I think he's trying to do the right things, but for potentially the wrong reasons ... or do the wrong things for the right reasons, I should say!"

Led Zeppelin are being sued for plagiarism over their hit 'Stairway to Heaven'.
The band have been served legal papers on behalf of late song-writer and guitarist Randy California from the band Spirit, who claimed for years the track's opening notes were lifted from their track 'Taurus'.
Attorney Francis Alexander Malofiy, who is representing a trust for Randy, told Bloomberg Businessweek: "It's been a long time coming.
"The idea behind this is to make sure that Randy California is given a writing credit on 'Stairway to Heaven'."
Businessweek quotes an estimate that by 2008 the track had earned at least $562 million.
Spirit played shows with Led Zeppelin in 1969 and fans have talked about the similarities between the songs for years, claiming Jimmy Page used the band's riff.
He allegedly wrote 'Stairway to Heaven' in 1970, two years after 'Taurus' was released and a year after the band shared stages at gigs across the America.
According to the band's bass player Mark Andes, Spirit always included 'Taurus' in their sets.
He said: "It was such a pretty moment. It would typically come after a big forceful number and always got a good response."
In 1997, Randy went public with his claims and said 'Stairway to Heaven' was a "ripoff".
He said: "The guys made millions of bucks on it and never said, 'Thank you,' never said, 'Can we pay you some money for it?' It's kind of a sore point with me."
Those close to Randy say he never sued because he didn't have any money back then and the band "thought the statute of limitations was done."
As Led Zeppelin prepares to release remastered deluxe versions of their original albums, including the track, Randy's trust is taking action with a copyright-infringement suit and an injunction that would block the reissue.
