VIDEO: NICKI MINAJ ON DAVID LETTERMAN

Last night on David Letterman Nicki Minaj performed her song "Check It Out" and will.i.am made a special appearance.

Watch the performance after the jump:

This song and performance was very unique & I noticed how a lot of Nicki Minaj haters are always focused on the faces she makes while rapping and how she raps, but if you listen closely to her lyrics she is tell the haters that she ain't going know where.
