'SNL' will miss Bill Hader, and Hader will miss the show, too -- especially when Justin Timberlake hosts.

One person he won't be pining for, though? Justin Bieber, whom he describes as pretty much a high maintenance pain in the ass.

When sitting in on Howard Stern's show, the King of All Media asked Hader what he thought of the 'Suit & Tie' singer. "He's great," Hader gushed. "Also, guy doesn't show up with anybody. It's just him."

Unlike that other Justin.

"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. You were trying to fight around all these people to get dressed," he griped.

"Timberlake, it was just him. He's a real class act, that guy."

There are other hosts Hader won't miss, though his rationale should be taken with a grain of salt and the humor with which it was intended -- though their identities probably won't surprise anyone that much, because they're the same people you probably love to hate, too.

"Ashton Kutcher tried to have sex with that llama we keep backstage and Tom Brady used one of Lorne's suits as toilet paper, even though we bought him the fancy stuff," Hader said. "And Gwyneth Paltrow, well, she was the worst of all. She gave the writers the idea for 'The Californians.' We hated it, too."
