Justin Bieber - Justin Bieber Or Natalie Portman: Who Was Funnier On Snl's Digital Short?

Justin Bieber didn't host the most recent Saturday Night Live, but he certainly stole the show with a surprise appearance in the show's 100th Digital Short. Twitter sprang into action as the teen sensation - dressed in a tuxedo - joined Andy Samberg and Jorma Taccone in the clip to celebrate the milestone.

Bieber was seen dancing enthusiastically before the comedy duo sang, "Tonight we're going to suck our own d****". Justin's face dropped before he bluntly asserted, "What? That's disgusting", adding, "I was tricked into doing this!". Elsewhere in the clip, Oscar-winning actress Natalie Portman reprised her role as a trash talking rapper, declaring, "Yeah I had a baby, but I'm still crazy". As the video became even more bizarre, Jon Hamm appeared as a shirtless saxophone player with a ponytail, later thrusting against Bieber himself. Saturday's episode was hosted by former Saturday Night Live star Will Ferrell, with a musical performance from Usher. The season finale airs this week, with Rolling Stones frontman Mick Jagger taking on hosting responsibilities, and musical guests including Foo Fighters and Arcade Fire.

Bieber's third studio album 'Believe' will be released on June 19, 2012 in the U.S. and June 18 in the UK.
