Sharon Osbourne, wife of troubled Black Sabbath front man Ozzy has spoken out about the couple’s experience in therapy.

Ozzy has struggled with addiction to alcohol and drugs for years and admitted last year that he had relapsed.

At the moment the singer is clean but Sharon has explained that things didn’t go smoothly initially in therapy.

“The sessions were supposed to last an hour and a half and Ozzy spent half an hour peeing.

"He'd be up and down and then look at his belly. He has this habit of lifting up his shirt, looking at his belly because he has taken a p**s and thinks his belly will be flatter. So he goes back and forth... the belly and the p**sing,” she revealed to newspaper The Mirror.

“Then he starts to hum. He doesn't have to pee. It is an excuse, because his attention span is two seconds.

“During looking at his belly and peeing, he is looking at his watch. At exactly an hour and a half, he goes: 'We are off now. Bye, see ya.

"He is out the f**king front door. Car door open. I am still trying to get my handbag together and he is in the driveway. We went for a month. That was it. It is not worth it. It was too much stress.”

Sharon has admitted that she was close to divorcing Ozzy at the time.
