Taylor Swift's lucky number 13 has unluckily landed her in legal troubles, as she is being sued by Apparel Company Lucky 13 due to trademark infringement.

E! News reported, that the Grammy winner is being sued by the Orange County-based apparel company for infringement. According to the lawsuit, which was filed early Tuesday morning, the singer had used Lucky 13's federally registered trademarks without authority.

Taylor Swift sells merchandise such as t-shirts with "Lucky 13" written on them through her online store.This made Lucky 13 Company owner Robert Kloetzly clearly unhappy. TMZ reported that Kloetzly has been marketing clothes and accessories to a young rock 'n roll crowd since 1991, and he feels that Taylor Swift is stealing his business, by slapping "Lucky 13" on her own clothing line (photo). Kloetzly also claimed to have already contacted the singer's party several times with no resolution.

In the lawsuit, which TMZ had obtained, Taylor Swift is being described by Kloetzly as a singer who likes "fast cars and dangerous men who drive them inappropriately," which unluckily also speaks for the marketing target of the company. Furthermore, Taylor Swift's music video for "I Knew You Were Trouble" could be an ad for the company, because it "depicts stylish, attractive, tattooed individuals in provocative situations." According to the lawsuit, Kloetzly wants Taylor's merchandising site shut down. He also wants all the profits her merchandise has gained so far given to him, or payment for the damages to his company, whichever is greater.

Taylor Swift hasn't made her affinity towards the number 13 a secret. The superstitious number plays a big role in the songstress life and considers it as "not an unlucky number" (photo). She has been seen several times on stage with the number drawn on her hand and her Twitter name includes 13 as well.

The singer had explained the importance of the number 13 to MTV News.

"I was born on the 13th. I turned 13 on Friday the 13th. My first album went gold in 13 weeks. My first No. 1 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," she explained.

Lastly Taylor Swift added that "whenever a 13 comes up in my life, it's a good thing."

Well, apparently not this time with the lawsuit pressed against her.
