Jesse James checked into rehab to help get over his abusive childhood.

The motorcycle entrepreneur - who allegedly cheated on estranged wife Sandra Bullock with at least four women - entered Arizona’s Sierra Tucson Rehab Facility last month and while he was getting treatment for sex addiction and anger management he also wanted to stop his violent father dictating his personal life.

The 40-year-old star - who lived with his dad Larry James following his parents’ divorce - told Nightline, “My whole childhood I never had a chance to be a kid. “I remember the clenched-teeth, strained-neck look on his face. He beat my a*s pretty good a bunch of times. Football star, bike builder, Monster Garage TV star-all that stuff is a huge smokescreen so people won’t see that I’m a scared, abused kid, a seven-year-old.”

However, Jesse’s father has denied the allegations.

Jesse - who has three children from previous marriages and was in the process of adopting a baby boy with Sandra when the cheating allegations surfaced - admits his past had ruined his ability to be a good husband to the Oscar-winning actress. The biker - who has since left rehab - said, “I don’t think I have a sex addiction where I’m running around trying to have sex with everyone and I can’t stop. I think I do things to sabotage myself, including having extramarital affairs, texting, over-working myself, injuring myself, doing stunts and stupid things. I do a lot of things in my life that I shouldn’t be doing that aren’t conducive to being a good husband. The affair is just one of them.”

Sandra has now adopting four-month-old Louis as a single parent and Jesse is resigned to the fact their marriage is over: “I hope of saving some kind of relationship with Sandy but we’re getting divorced.”
