Jesse James broke down in court on Wednesday (14.06.10).

The motorcycle entrepreneur - who split from Oscar-winning actress Sandra Bullock after an affair with tattoo model Michelle 'Bombshell' McGee - admitted in a custody hearing with ex-wife Janine Lindemulder he had hit rock bottom in recent months.

When asked if he had reached his lowest point, he said: "Yes. To some extent."

Discussing his stint in rehab earlier this year, he added: "I am continuing treatment."

The 41-year-old star also said he became an alcoholic at the age of 14 or 15 as a result of childhood abuse from his father.

He told the court: "I've been living in the shadow of that my whole life. I've always hated my sister, but as bad as I got beat, she got it even worse.

"I drank until I was 30. That was a big band-aid for the pain I was in."

Jesse was in court to fight with his ex-wife over the custody of their six-year-old daughter Sunny, whom he wants to move to Texas.

Speaking earlier this week, Jesse revealed his young child had become agitated following increased contact with her mother since she had been released from a halfway house on June 3.

He said: "The more contact she has with her mom, the more fear she has to sleep in her own room."
