Sophia Grace and her backup dancer Rosie became Internet superstars last week when their YouTube video, in which they sing Nicki's "Super Bass," went viral.

Always the one to make dreams come true, Ellen DeGeneres invited the girls, who are from Essex, England, on to the show (they wore their adorable pink princess costumes from the video) to perform the song.

But, of course, she also got Nicki to come on the show and surprise the girls! When Nicki walked on to the stage, Sophia Grace screamed and jumped into Nicki's arms.

"You are incredible," Nicki told Sophia Grace. "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."

Ellen asked the girls if they knew what the song was about and they didn't.

"No, I just learned the words really quickly," the 8-year-old explained. "And I like the video because it's got a motorbike made of ice, and pink! Everything is pink, I just love pink!"
