Nicki Minaj & Kanye West's "Monster" Teamup

Giving her audience quite the surprise, Nicki Minaj was joined by Kanye West onstage at her concert last night (August 2).

The “Super Bass” songstress, who is currently opening for Britney Spears' "Femme Fatale" tour, was joined by Mr West during her head-spinning verse on “Monster.”

The track is from Kanye’s 2010 magnum opus, “My Beautiful Dark Twisted Fantasy.”

Minaj tweeted after show's end, “New York!!!! Feels good to get this love @ home! U guys have NO idea how honored I am. Thanks to @kanyewest 4 cmng out & shutting it DOWN!”
