Guess who's back? Nicki Minaj, as her diabolical rap alter ego Roman Zolanski, returns with a new song called 'Roman in Moscow.'

The Grammy-nominated rapper unveiled the song on her official website Pink Friday on Friday (Dec. 2). Roman is unlike the black Barbie that we all know and love -- she has a potty mouth and bravado big enough to knock out an elephant.

Over a hectic production by SAROM and Street Runner, Roman introduces herself to her fans as she spits hashtag raps about her private parts, fake rappers and uses the b-word like it's going out of style. "Heroin, this s--- is lethal / Roman: this is the sequel / Moscow: that’s where I came from / Under, he’s fully charged / Your favorite rapper / Probably suck / As for me? / Icy, hockey puck," she snarls.

Near the end of the song, she threatens any rapper (*cough* Lil Kim) who has the cojones to challenge her on the mic. "Roman’s back, b---- / I f---ed up your life last year at this time, remember dat?" she cautions.

Nicki's, oops, excuse us, Roman's track 'Roman in Moscow' certainly has us anticipating what her next move will be in 2012. As we previously reported, Minaj plans to drop her new album 'Pink Friday: Roman Reloaded' on Valentine's Day. Can you feel the love, Barbiez?
