Ellen, who turned 57 on Jan. 26, snapped a selfie with the stars behind the scenes. It wasn't filled with quite as many celebs as her famous Oscar selfie, but it’s still awesome to see stars smiling together.
Well, not all of them were smiling. Kayne had an ear to ear grin, and even the famously morose Smith gave a subtle grin, but Justin couldn't help but try and look cool.
Of course, his stony demeanor might have had something to do with his nerves. In a video Bieber posted to Facebook, the "Boyfriend" singer admitted that he had been incredibly nervous while filming the episode because he "was afraid of what people [were] thinking" about him, and he didn't want to come off as "arrogant."
While this selfie might not help with that, the pop star did send a few heartfelt tweets to Ellen wishing her a happy birthday and apologizing for his nerves.
You were perfect. Thanks for surprising me! RT @justinbieber: Good seeing u today @TheEllenShow. Happy birthday! Sorry I was so nervous
