Ozzy Osbourne's Ex-Mistress Michelle Pugh Opens Up About 4-Year Affair: 'He Gave Me the Greatest Love of My Life'

Michelle Pugh was thrust into the spotlight earlier this year when her affair with Ozzy Osbourne was revealed, and now the celebrity hair colorist is opening up for the first time about her relationship with the rocker.

“When I say he gave me the greatest love of my life, I mean it,” she tells PEOPLE exclusively about Ozzy, whom she claims first pursued her one year after she first colored his hair in late 2011. “He made me feel like the most beautiful and worshipped woman in the world.”

Ozzy – who earlier this month told Good Morning America his 33-year marriage with wife Sharon, 63, was “back on track” after the two split in May – insists the relationship with Pugh was a purely physical one that resulted from his sex addiction.

“He is sorry if Ms. Pugh took their sexual relationship out of context,” the singer’s rep tells PEOPLE exclusively in a statement. “He would like to apologize to the other women he has been having sexual relationships with. Since his relationship with Ms. Pugh was exposed, Ozzy has gone into intense therapy.”

However, Pugh maintains Ozzy, 67, was “unhappy” in his marriage and “consistently and willingly and generously” gave her “his love.”

“What attracted me to him? Chemistry,” says Pugh. “We just had it. It’s that indescribable thing in life, and you can’t deny it. And he didn’t.”

For Michelle Pugh’s exclusive interview about her affair with Ozzy Osbourne and how the rocker is doing now, pick up the latest issue of PEOPLE, on newsstands Friday.

Aside from their physical relationship, Pugh says the duo also connected on an “emotional level” and would have long discussions about their “shared passions” for painting, history and current events. “My relationship was more with this really nice, sweet, funny and cool guy … John from England,” describes Pugh.

Acknowledging she is no longer in touch with Ozzy, Pugh says it’s a “struggle every day now” for her when she wakes. “I wake from my dreams, which some nights he’s in, and for a minute when I wake I’m peaceful,” she says. “Then the absence sets in. It’s horrible.”

Even so, the hair colorist says she has no ill will towards her former lover.

“He is a grown man. He is capable of making the decision to be with me. If he has chosen to not be, that is fine. I accept it and move on,” she says. “But he has been my best friend for the last few years, so of course I am grieving the loss for that.”

“I still love him,” continues Pugh. “And I would never exploit the truly personal and private parts of what we had. That’s not me. I’m going to stand tall and proud and say, ‘This is me. I’m not ashamed.’ I fell in love with a man that gave me the love I never knew I could receive.”
