Celebrities Sing "Since U Been Gone"

Celebrities like Jimmy Fallon, Meghan Trainor, John Oliver and of course, Kelly Clarkson sing along to her song "Since U Been Gone". Some celebrities really get into and really BELT out the notes (*COUGH* John Oliver *COUGH*).

I won't lie, I sing like Shaq where I make the song as sensual and provocative as possible haha
