The Mean Girls star launched Sevin Nyne last year (09) after reportedly spending three years developing the product alongside entrepreneur Lorit Simon for the chemist's company Lorit.
Simon and Lohan were hit with a breach of contract suit in July 2009 by Florida-based executives at White Wave International Labs, who claimed the pair copied their formula for the spray tan after one of its chemists showed them samples of their creations months before.
Now Lohan is trying to distance herself from Simon and the Lorit firm, claiming she was just the face of the brand.
In new court documents obtained by TMZ.com, Lohan states: ""Although I have been a spokesperson for Lorit, LLC, and its Sevin Nyne product, I had no involvement in where or how the Sevin Nyne product is marketed and sold or in the marketing strategy for the product.""
Lohan's lawyers want the case dismissed because the Florida court has no jurisdiction over the star, who lives primarily in Los Angeles.
She adds, ""Although I occasionally visit Florida for pleasure, I have never had any acting jobs in Florida... ""
