Nicki Minaj was last night's (January 29) guest star on Saturday Night Live, but the rapper defied all expectations of a sexy performance and appeared in an unusual skit. 

Dressed in a pair of nerd glasses, blonde wig and a school uniform style outfit, she made her SNL debut as part of a Lonely Island music video called 'The Creep'. During the short video, Minaj hides in a locker to spy on half naked men and lunges lustfully at a corpse at a funeral. 

The 'Check It Out' rapper recently explained to MTV News how excited she was to appear on the iconic chat show:

"Being a part of 'Saturday Night Live' feels absolutely incredible. I still don't even believe it's true, I'm not even going to believe it's really happening until — well, I'm going to DVR it, because I can't watch it, because I'll be on it,"

"But until I see it back on DVR, I'm not even going to believe I was really on the show. This is epic, this is monumental, this is historic stuff."
