Actor Bill Hader has spoken about the crew Justin Bieber took with him to Saturday Night Live.

The Canadian popstar has often appeared on the iconic US comedy show but Hader - who appeared on the series between 2005 and 2013 - wasn't too impressed.

Speaking to Howard Stern, the actor - who has appeared in such films as Superbad and Knocked Up - said that SNL's backstage was overrun by Bieber's entourage when the singer hosted the show in February. He said:

"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."

Justin Timberlake, however, was a more modest host of the show, it seems. Hader added:

"Timberlake, it was just him. He's a real class act, that guy...He's great…Also, guy doesn't show up with anybody. It's just him."
