One lucky fan can steal Mariah Carey's style! Last fall, the singer asked fans to design a dress that was inspired by her new Luscious Pink fragrance. Julian Contreras of San Jose, Calif., won the design competition, and Mariah wore Julian's sexy pink dress to dinner with husband, Nick Cannon, in April. There are only three copies of the dress in existence, and now you have a chance to win one! The slinky gown is being auctioned off on eBay and all proceeds will go to the breast cancer charity Susan G. Komen for the Cure. Bidding ends on May 30.
