He’s seen a ton of celebrities come through the halls of “Saturday Night Live” over the years, and Bill Hader** told Howard Stern** he’s a huge fan of one in particular.

The hilarious comic, who just left SNL, said that Justin Timberlake** was the epitome of a talented, gracious star.

“He's great. Also, the guy doesn't show up with anybody. It's just him,” began Bill, who also shared that he couldn’t stand it when Justin Bieber** came to the show.

"Justin Bieber showed up with like 20 guys. He had a guy holding a slice of pizza. A guy holding a Diet Coke. You're trying to fight through all these people to get dressed. Timberlake, it was just him. He's a real class act, that guy."
