London:Singer Ozzy Osbourne says he is undergoing "intense therapy" for a "sex addiction" that nearly resulted in the disintegration of his marriage to Sharon Osbourne. The 67-year-old said in a statement that he was "mortified" at the effect of his behaviour on his family, reports telegraph.co.uk. The announcement came after hairstylist Michelle Pugh told the media that she had a "very real relationship" with Ozzy and that it lasted four years. “Over the last six years, I have been dealing with a sex addiction. I'm sorry if Ms. Pugh took our sexual relationship out of context. I'd also like to apologise to the other women I have been having sexual relationships with,” Ozzy said in a statement. “Out of bad comes good. Since the press exposed this, I have gone into intense therapy. I am mortified at what my behaviour has done to my family. I thank god that my incredible wife is at my side to support me,” he added. Earlier this year, Ozzy moved out of the family home, with Sharon suggesting in May that their 34-year marriage could come to an end. However, the couple later indicated they were back together.
