Nicki and Katy share many things in common: pink hair clips, cupcake dresses, bright lipsticks, and gossipy phone calls. Oh, and producers. Because when Nicki's making pop songs, she goes to Max Martin and Dr. Luke, the same showhorses in Katy Perry's stable. Ha-ha-ha, they're exactly the same! Oh wait, no they're not, because Nicki is absolutely killer as a rapper, upstaging everyone in her guest spots: Kanye West to Lil Wayne, Drake to Big Sean, Busta to...well, everyone. Katy's a non-factor in the hip-hop world, except as a way for Rick Ross to describe his cocaine. Even still, Ellen's two wee scamps Sophia Grace and Rosie probably have a very tough time deciding who they like better.
