Nicki Minaj has a several identities -- Nicki Lewinsky, Roman Zolanski, Harajuku Barbie -- but she left those all home for her surprise performance at Barclays Center for Powerhouse 2013. Instead, Minaj played herself, coming out during Meek Mill's set, and performed several of her features on her pals' tracks. VIBE was in the pit during her performance of DJ Khaled's "I Wanna Be With You" and the Cash Money banger "Tapout." Never mind that her frenemy Lil Kim was in the building too. Ms. Minaj, dressed in a Nicki Minaj collection jumpsuit that showed off her curves, kept her claws on the mike. Watch as Minaj struts her stuff and assists Meek Mill during Powerhouse 2013.
