Is Barack Obama 'jealous' of Justin Bieber?

The president seemed to make a "derisive facial expression" when a crowd went mad for the floppy-haired teen idol. Scrutinize the video "evidence" here

Is it possible the President of the United States feels threatened by 16-year-old pop sensation Justin Bieber? At the annual White House Easter Egg Roll, Obama appeared to make a "derisive facial expression and mocking hand gestures" when his wife introduced the singer and the predominantly young, female crowd squealed in delight. Clearly, the president's "ego took a hit," speculates Dan Amira at New York Magazine. "When Justin Bieber is in attendance... [Obama] might as well not even exist." Has the president's self-esteem been permanently damaged? Uh, no, says Aylin Zafar at the Atlantic. Watch Obama's "jealous" reaction at the 2:20 mark in this video:
