It seems there’s always one celebrity getting sued by a beauty company. Now, it seems to be Lindsay Lohan’s turn to face some legal issues.

In a lawsuit filed in Tampa, Florida, chemist Jennifer Sunday claimed Lohan and her business partner, Lorit Simon, stole the formula for Sevin Nyne, a Lohan-endorsed fake tan which launched in the states earlier this year. According to the suit, Simon and Sunday had been hammering out details of the tanning spray, but weren’t able to agree on pricing.

“The next thing we know, Lorit Simon and Lindsay Lohan are partnering and Ms. Lohan is taking credit for developing this formula, which she indeed had no role in,” Sunday’s attorney, Marcia Cohen, told the St. Petersburg Times.
