Yes, it reached No. 2 on the charts and went double platinum in the U.S., but this is how Ariana Grande knows her single 'Problem' is a really huge hit: pint-sized Sophia Grace Brownlee covered it!

Yes, the more vocal half of the adorable 'Ellen DeGeneres Show' standouts Sophia Grace and Rosie gives Ari's summer anthem a try in a new video posted to her YouTube channel.

In the clip, the 11-year-old Brit is caught belting out a few seconds of the tune while she sits on the floor, peeks at her phone and works on a bracelet. The mini multi-tasker seems oblivious to the camera creeping around the corner and looks up a bit stunned when the its operator says her name. She smiles and also stops singing, which is unfortunate because we'd love to hear her sing the rest of the track!

We've already heard her crush songs from 'Frozen' and hits by many artists, including Nicki Minaj and Adele, but her vocal prowess here is still amazing. And, surprisingly, because the video is in black and white, we don't see her wearing her usual pink. And there's not a princess crown in sight!
