Sharon Osbourne has addressed Justin Bieber's recent bad behaviour during an interview with Chelsea Lately.

On Monday's episode of the chat show (February 10), the former X Factor judge was quizzed about what she would do to Justin if she was his manager, to which Mrs. O replied: "He would have to go to a hospital to get my foot out of his ass.

"And after they pried my foot from his ass, it's all about the music. If you make great music, I'll accept anything. If you're a great artist, I'm not so judgmental. But when you do floppy, poppy, disposable music, I don't care."

She continued: "For me, he doesn't do anything that's going to stand the test of time."

Shazza then concluded: "If I seriously managed him, I would put him in the studio until he came out with a great album and then, it gives you a license to misbehave."

It is not the first time Osbourne has criticised Bieber, with Sharon stating in 2012 that she didn't believe his fame would last.
