Except when she's Roman Zolanski, her gay male alter ego, who spits saucy verses at warp speed. Or the character Nicki Lewinsky, who cozies up to President Carter -- better known as superstar rapper Lil Wayne -- on a handful of salacious mix tape tracks. She raps about signing her fans' boobs in a bugged-out Valley girl accent. She's the first female hip-hop artist to hit number 1 on Billboard's top rap singles chart since 2003. She's stolen the spotlight on songs with pop heavyweights Mariah Carey and Usher. And she's done it all while playing hip-hop's most dangerous game: sexuality roulette.
