WATCH: Meghan Trainor, Mumford & Sons and More Sing ‘Since U Been Gone’ on ‘Tonight Show’

Kelly Clarkson’s hit “Since U Been Gone” is song that everyone knows. We’ve heard it a million times, so it should be easy to sing it word by word, right?

Jimmy Fallon put a group of A-listers to the test. In his latest segment “Turn It Up Challenge”, Fallon gave his guests noise-canceling headphones and let them belt out the tune. The results are pretty hilarious since they couldn’t hear themselves.

Check out the video below.
