Graham Norton remarked on his show (The Graham Norton Show, silly Americans) that Jessie J is the greatest talk show guest because she does "party tricks." Which tricks, you ask?
Nothing requiring a "ping pong ball," said Norton. Cheeky!
No, actually, Jessie J demonstrated that she can sing with her mouth closed, and the lyrics of "Bang Bang" are surprisingly clear as she does it! Perhaps she'll be giving Jeff Dunham a run for his money.
