Katy Perry is indeed a chameleon in the POP arena.  Just recently, though, the pop queen threw her Yankee fitted into another arena--the HIP-HOP Arena!  At a performance for BBC Radio 1 in London, Perry did her best Jay-Z and Kanye when she performed an intersting version of their hit 'Niggas in Paris'!  But of course, she substituted 'Ninjas' for the other word.... At least thats what it SOUNDS like she did...  TAKE A PEEP!!!
