Well it’s a good thing Bill Hader left Saturday Night Live, because this future run-in would be totally awkward!

After Bill left his home on SNL, he stopped by The Howard Stern Show to dish on which celebrity hosts were the best and the ones that well, were a bit difficult to work with. Turns out Justin Timberlake is fantastic and Justin Bieber… not so much!

Getting asked about JT hosting the sketch comedy show five times, Bill said, “He’s great… also, guy doesn’t show up with anybody. It’s just him.” But one person who is opposite of that is Bieber. “Justin Bieber showed up with like 20 guys. And every time, backstage is a very small constructed place, he had a guy holding a slice of pizza, a guy holding a Diet Coke,” he said. “You were trying to fight around all these people to get dressed. Timberlake, it was just him. He’s a real class act, that guy.”

Maybe Bieber is just so used to having a whole team surrounding him all the time (being the biggest pop star in the world can do that to you). But let's chalk this up as another celebrity and their not-so-nice comments about the Biebs!

What do you think about Bill’s comments about Bieber?

Would you have expect that from the pop star?
