American pop singing star Mariah Carey is worried fans could confuse her with American porn star Mary Carey and filed suit Friday in Los Angeles to prevent the star of movies such as “Double Air Bags 11″ and “Boobsville Sorority Girls” from trademarking her similar-sounding stage name.

The adult film actress, whose real name is Mary Cook, said Friday she would not be intimidated by the international superstar and will continue her trademark application. She began using the stage name Mary Carey in 2002 and ran for California governor against Arnold Schwarzenegger. She filed the trademark papers earlier this year. Comparing the two bodies I guess nobody will confuse these two by the way!
