Los Angeles: Singer Justin Bieber has been tagged as the "worst-behaved" guest on "Saturday Night Live" by two cast members of the show.
Bill Hader and Jay Pharoah, who are no longer a part of the long-running comedy sketch series, said the "Love Me" singer was probably "in a bad place" at the time he appeared on the show, Vulture reported.
The duo was answering questions from phone-in when they were invited by Andy Cohen on his show "Watch What Happens Live", when one of the audience members asked who they considered to be the "worst-behaved" celebrity ever to appear as a guest host or musical guest on "SNL".
"We both know, dog," Pharoah said.
To which Hader quickly replied, "Yeah, it was Bieber... He was just in a bad place. Maybe he's in a better place, but then he was... It was rough."
"Everyone's usually on great behaviour. Everyone's usually very excited and on great behaviour, most time it's 100 per cent, so that's why I think Bieber's the only one in my experience. And I think it was just he seemed exhausted or at the end of a rope," he added.
Bieber appeared as a host and musical guest in 2013 to promote his album 'Believe'. His name was mired in a controversy, including a vandalism charge in Brazil.
