Justin Bieber needs a good slap: Sharon Osbourne

 TV personality Sharon Osbourne thinks pop sensation Justin Bieber "needs a good slap" for his bad behaviour.

The 61-year-old outspoken music manager, who has managed her rock star husband Ozzy Osbourne for over 30 years, said the troubled pop star is surrounded by the wrong people, who constantly allow him to get away with behaving badly, reported Contactmusic.

"He needs a good slap. He is surrounded by the wrong people. I would say, 'Put yourself in the studio and don't come out until you have a great body of work'," she said.

The candid music expert went on to dismiss the Canadian heartthrob's music as being "floppy, poppy (and) disposable" and thinks he needs to put out great music in order to have a "licence to misbehave".
