Amy Winehouse's boyfriend has been cheating on her for months, it has been claimed.

Reg Traviss' ex-girlfriend, burlesque dancer Raven - who he was pictured holding hands with last week - says she has continued sleeping with the filmmaker throughout his four-month romance with the troubled singer, except for a brief split.

Raven said: "I've spent pretty much every day with him. I'm surprised we haven't been spotted together before.

"When Amy and Reg were first pictured together, he called to warn me. He said Amy had grabbed his hand as they left a restaurant, but they were just friends."

The 25-year-old blonde called a halt to her relationship with Reg in July after realising he was more than just friends with the singer, but they reconciled on August 5 after he bombarded her with calls and messages.

Raven added: "He told me that he loved me, that he only wanted to be with me, have babies and get married.

"I believed him. He told me he had stopped talking to Amy. I was still in love with him so I agreed to give our relationship another go."

However, after seeing pictures of the director with the singer last week, Raven ended their relationship for good.

She told Grazia magazine: "I phoned Reg and asked if he had met with Amy after he'd run away from the pub. He denied it at first, but then finally told me he had. And the next day I saw pictures of them acting like a couple. I've ended things."

The performer has now urged Amy to follow her lead and dump Reg.

She added: "I can't believe anything he says.

"I really feel for Amy as she's obviously a vulnerable person. He's going to break her heart.

"My advice to Amy would be that she ended it like I have."
