Until now they have wowed the world with adorable renditions of popular celeb songs, but now YouTube sensations Sophia Grace Brownlee and Rosie McClelland have performed a hit of their very own.

The young British duo performed their first original song, a rap about Disneyland, on the Ellen Show.

Raising the cute-o-meter once again in their trademark tutus, eight-year-old Sophia and Rosie, five, impressed the Ellen audience with their last performance for the talkshow host.

The song, which features the names of many of Disney's most famous characters, highlighted the girls' star potential.
