Jesse James has been branded a "chronic cheater" by his ex-wife.

Janine Lindemulder - who separated from the motorcycle enthusiast after one year of marriage in May 2003 - insists she wasn't surprised to learn the 'Monster Garage' presenter had bedded tattoo model Michelle 'Bombshell' McGee while current spouse Sandra Bullock was away shooting 'The Blind Side'.

Janine - who has five-year-old daughter Sunny with Jesse - said: "He's a chronic cheater. I feel sorry for Sandra because she was so in love with Jesse that she was blind and gullible. She once said, 'I finally have a man who has my back.' And all I could think was, 'No. You have this man who does it behind your back.' "

Janine claims that Jesse was unfaithful to her soon after they tied the knot and he refused to change his behaviour throughout their union.

She also claims he propositioned her over the phone when he was Sandra.

Janine said: "I remember at one point, about six months after he started dating Sandra, when he asked me to come by the shop. I told him, 'No way.' Later, he texted me, 'Thank God you didn't come by, because we would have been bad.'

"His famous line was, 'Tell me something nice.' He would say he'd had a rough day and wanted you to tell him something nice. It was hard to say no to the guy."

The former porn star also alleges Jesse told her he regretted marrying Sandra just weeks after they tied the knot in July 2005.

Speaking of a phone call she received from Jesse shortly after the wedding, Janine told In Touch Weekly magazine: "He said, 'I want to come up to Oregon. I think I made a huge mistake.' "
