Nicki Minaj and will.i.am landed their spaceship at the Ed Sullivan Theater to perform their futuristic collabo “Check It Out” on Monday’s “Late Show with David Letterman.” The animated femcee bounced around the stage wearing a black patent bolero jacket with striped jersey draped pants by Mark Bouwer, while the Black Eyed Peas frontman donned a space-age suit and plastic hair. This is the duo’s second performance of the song following last month’s VMAs. Watch them rock late night below.
