Watch Jessie J Sing “Bang Bang” With Her Mouth Closed
I have to admit, I tried singing "Bang Bang" after I watched this with my mouth closed and it didn't end well. I nearly passed out. Jessie J has one of the best voices in pop music right now in my opinion, open or closed mouth. She was on the Graham Norton Show earlier this week and sounded just as fantastic with her mouth closed as she does when it's open. Check it out and try it yourself.
