Sophia Grace and Rosie have become pint-sized super-stars after Ellen discovered the video of the two rocking out to Nicki Minaj's "Super Bass" on YouTube.

The pair went on Ellen shortly after she found the video, and were thrilled to be able to meet their hero Nicki Minaj. They returned to sing their rendition of Adele's "Rolling In The Deep" a few weeks ago, sporting new tutus.

Well, I wasn't jealous of them until now. Sunday night, Sophia Grace and Rosie were on hand as Ellen's special correspondents for the American Music Awards! From the video, it's hard to tell who's more excited, Sophia and Rosie, or the stars that they met. Check out the video after the jump!
