Call it a tale of two Justins.
"He's great," Hader said about SNL's frequent host. "Also, the guy doesn't show up with anybody. It's just him."
Unfortunately, Hader didn't exactly have the same praise for another of this season's hosts.
"Justin Bieber showed up with like 20 guys," Hader recalled. "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."
Hader left as a cast member of Saturday Night Live last weekend after eight seasons on the show.
