Nicki Minaj got an early jump on Halloween Friday night when she turned up at the 1 OAK nightclub in Las Vegas in a fairy princess costume. Minaj played host to the Nicki?s Funhouse event, which offered contest winners the opportunity to party with the ?Pinkprint? rapper. With a sweet smile on her face, puffy white skirt and a sparkly tiara, Nicki belied her innocent fairy image by displaying some serious cleavage and sky-high heels.
