Sophia Grace and Rosie perform Nicki Minaj's "Starships" on Ellen

It was a Minaj song, "Super Bass", that brought Sophia Grace and Rosie to international attention in 2011 when a video was uploaded to YouTube of the cousins singing and dancing to the tune, and they tackled another of their idol's songs when they returned to Ellen's stage.

Little Rosie has gained a lot of confidence, it seems, while Sophia Grace is as loud-mouthed and lovable as ever.
