Justin Bieber calls his guitarist ‘terrible’ during awks performance

Another day, another Justin Bieber saga.

If he's not stirring it up on social media, he's slamming his own band during live performances, and it doesn't sound like people are too impressed.

During a fairly ropey live set for BBC Radio One's Live Lounge, the singer dropped the F-bomb before calling his guitarist out on mistakes because, you know, he can.

Remarking on the musician's playing during Love Yourself, 22-year-old Justin told listeners: "He's broken his finger, so he's not usually this terrible."

Selena's ex took to Twitter to explain that hs nerves got the better of him during the performance, writing: "I don't usually get nervous but tonight I was thrown off and I was."

I don't usually get nervous but tonight I was thrown off and I was. Sorry about that. Really wanted to be my best. Hope u all had fun

"Sorry about that," he added.  "Really wanted to be my best. Hope u all had fun."

Unfortunately for Justin, it doesn't sound like they did.

Taking to Twitter to comment on the set, one social media user wrote: "Justin Bieber sounds awful on live lounge, he's being so rude to the presenter too @BBCR1"

"Justin Bieber has zero crack and not an announce of personality," added another.

Ouch.
