Sophia, 8, and Rosie, 5, have already managed to, for a moment, steal the show on a Nicki Minaj track, which is pretty impressive considering that Nicki Minaj is Nicki Minaj and that "___________ raps Super Bass!" could be a standard headline by now. Where else could one go from here? To the biggest song of 2010-technically-but-really-2011, "Rolling in the Deep." Many times has it been covered; seldom has it been covered by performers in tutus.

The performance was on Ellen, by the way, and had an interview to go with. We recommend watching the whole thing, if only for the Halloween and champagne portions.
