Bill Hader was left less than impressed when Justin Bieber came on to host Saturday Night Live earlier this year.

Bill Hader Slams Justin Bieber

Hader names Bieber as won of the worst hosts he worked with during his lengthy tenure on Saturday Night Live in the new edition of Live From New York: An Uncensored History of Saturday Night Live , written by James Andrew Miller and Tom Shales.

“I really didn’t enjoy having Justin Bieber around,” Hader admits in the tell-all, according to the New York Post. “He’s the only one who lived up to the reputation. I think that’s the only time I felt that way in eight years.”

Hader’s opinion was shared by other members of the SNL cast who worked with the pop singer. Kate McKinnon, for one, noted that he wasn’t the best sport when it came to weathering an impression of himself.

“Bieber wasn’t too upset by my impression of him,” revealed McKinnon. “But he wasn’t pleased.”

The passage in Live From New York is not the only time that Hader has spoken out about his experience working with the "Beauty and a Beat" singer. Back in May, Hader revealed that Bieber came with a sizeable entourage that made it difficult to navigate the backstage area.

"Justin Bieber showed up with like 20 guys. He had a guy holding a slice of pizza. A guy holding a diet coke," he laughed in an interview with Howard Stern. "Going around stage, you're trying to fight through all these people to get dressed."

Timberlake, Hader noted, didn’t bother with an entourage. "The guy doesn't show up with anyone. It's just him,” said Hader, who called Timberlake “a real class act.”
