A lawsuit has been filed in a Tampa, Florida federal court by chemist Jennifer Sunday against the actress, the St. Petersburg Times reports.
Sunday says that the Mean Girls actress and Nevada woman Lorit Simon stole the formula for Sevin Nyne. Lohan launched her product this summer, while lawyers for the chemist are looking into monies that she may have made from the business venture.
"We are certainly looking for the profits that are being generated right now from the product," attorney Marcia Cohen said. Sunday is suing Lohan, Simon and the star's Las Vegas-based company for theft of trade secrets and breach of contract among other allegations.
A representative for Lohan declined to comment on the matter.
