My favorite pint-sized Brits are at it again!

Sophia Grace and Rosie, first made popular by a viral video of them belting out Nicki Minaj's "Super Bass", have stolen the hearts of many Americans, including Ellen Degeneres.

They've been her correspondents at the AMA's and the Grammys, and have appeared numerous times on Ellen's show to show off the newest song they've learned. Check out their latest performance after the jump!

I have to say that while I love Sophia Grace, I'm really happy to see little Rosie come out of her shell recently.This time on Ellen, the girls took on another Nicki Minaj song, "Moment 4 Life".

Check it out!
