The cutest British rappers you'll see are back for one last hurrah ... and they're performing original material!

Best known for their YouTube rendition of Nicki Minaj's "Super Bass," Ellen DeGeneres favorites Sophia Grace Brownlee, 8, and her cousin Rosie McClelland, 5, took to the show "Ellen" today with a new performance -- an original song to thank Ellen for sending them on a trip to Disneyland!

Donning their trademark tiaras and wearing pink tops and fluffy white skirts, Sophia Grace raps out lyrics with references to Mickey, Minnie and Peter Pan, while her "hype girl" Rosie gets the crowd going with some clapping and dance moves.

The girls are headed back to England so this may be the last we see of them for some time. Check out their full farewell performance below!
