Bill Hader Explains Why Justin Bieber Was the Worst 'SNL' Guest: 'He Just Seemed Exhausted'

Bill Hader is spilling on why he believes Justin Bieber was the “worst-behaved” Saturday Night Live guest!

The 39-year-old comedian and SNL vet opened up during his appearance on Watch What Happens Live with Andy Cohen on Thursday (March 22).

“I mean, we both know,” Bill‘s fellow talk show guest Jay Pharaoh started after a fan question.

“Yeah, it was Bieber,” Bill agreed. “He just was in a bad place. Maybe he’s in a better place, but then he was in a very … it was rough.”

Bill added that, usually, celebrity guests are “on great behavior” and “everyone is very excited. Bieber is the only one in my experience – he just seemed like, exhausted or just at the end of a rope. He was just so huge.”

Justin served as the host and musical guest of a February 2013 episode. At the time, he was in the middle his Believe world tour and had recently split from his on-again, off-again girlfriend Selena Gomez.
