Ellen DeGeneres enjoyed Sophia’s and Rosie’s rendition of “Super Bass” so much that to invited the girls on her show yesterday, where they performed the song for the audience.

After their performance, Ellen surprised the girls by bringing Nicki Minaj on stage.

Minaj gave some advice to the girls, “You are incredible. I just want you to stay in school, the both of you. Music is beautiful, but I want you to stay in school. Put your books first and singing second.”
