Katy Perry Covers "N***as In Paris"

Pop star Katy Perry surprised the audience during a performance on BBC Radio 1's live lounge in England when, instead of performing one of her own hits, she donned a Yankee cap and offered up a cover of Jay-Z and Kanye West's hit "N***as In Paris."

It was slightly edited, of course.

Backed with a live band, Perry performed the cut much to the fans and hosts' delight, in a singsongy style--which she was quick to point out was 'not' rapping.
