Adorable British Tots Belt Out Their Rendition Of Taylor Swift's 'Trouble' [VIDEO]

Sophia Grace & Rosie appeared on Ellen this week to sing one of their favorite songs, "Trouble", by Taylor Swift. And might we add that this was probably their best performance yet!

These adorable girls aren't just the singing sensation from England but they're actually cousins! They share a love for performing but they couldn't be more opposite.

Sophia Grace Brownlee is the singer of the group. She rose to fame after posting a video of herself singing Nicki Minaj's "Super Bass" with her young cousin, Rosie. Sophia is more talkative of the two and her laugh is contagious. Rosie Grace McClelland is her sidekick - and, might we add, cute as a button. Although she doesn't sing she always performs with her cousin, giving Sophia Grace confidence. They're infamous for singing covers of well-known artists like Adele and Keri Hilson but these adorable girls even came out with their own original music: a rap called "Princess Swagger".

Sophia Grace rhymes about her love for Disneyland, cotton candy, and Ellen. We're not going to lie, it's probably the cutest rap we've ever heard.

When the girls visited Ellen they gave her a belated birthday gift (which they made out of Play-Doh), told the talk-show host about Rosie's adorable hamster named Fluffy (given to her by Father Christmas), and they saw their book "Tea Time with Sophia Grace and Rosie" for the first time.

Their reaction is too cute for words. They show us their favorite parts of the book as they flip excitedly through the pages.

We can't get enough of these two. Take a look...
