David Hasselhoff's ex-wife, Pamela Bach, claims her husband is an alcoholic who abused her during their marriage.
Pamela Bach made the accusation after hiring a former lawyer from the Anna Nicole Smith paternity suit.
She is fighting the 'Baywatch' actor for custody of their two daughters.
"I thought if he just wouldn't drink, everything is going to be OK," she told "Access Hollywood" in an interview. "He went to three rehabs. I supported that. He wouldn't stay, those are band-aids on the situation."
Bach attended a post-divorce hearing on Tuesday and when asked if she suffered any physical abuse during her husband's alleged drinking bouts, Bach said, "Yes, and it's not something I really wanted out there. It was like Jekyll and Hyde."
She also says she does not trust Hasselhoff with their daughters, Hayley and Taylor Ann, because she doubts he "can hold his disease at bay to not take that drink."
The former 'Knight Rider' star was in the news last year for incidents in London.
He accidentally cut a tendon in his arm in a bizarre shaving accident at a gym and a British tabloid said he was turned away from a flight departing for Los Angeles because he was drunk.
Hasselhoff played lifeguard Mitch Buchannon on 'Baywatch' from 1989 to 2000. He also starred in the 1980s TV series 'Knight Rider.'
