Lee, 35, pleaded no contest Tuesday to a felony charge of spousal abuse. That means he has violated probation and will spend between six months and a year behind bars. Sentencing's scheduled for May 20, and Lee is free on $500,000 bond until then.
After his stint in L.A. County jail (its celebrity alumni include Robert Downey Jr. and O.J. Simpson), Lee will likely be barred from seeing Pamela--who was in the Malibu Muncipal Courthouse to hear her ex's plea today.
Lee will be allowed to see his kids once a week, but the visits must be monitored. He was also ordered to lay off drugs. In exchange for Lee's plea, prosecutors dropped child abuse and gun charges.
Outside court, Anderson said: "Like I said, I'm very proud of Tommy. I'm happy that he took responsibility for this. And I think it's the first step towards healing. And I'm anxious for him to see his kids. And I'm sure his kids are anxious to see him."
Anderson, 30, has filed for divorce from the rocker, and the couple have no plans for reconciliation.
The ex-Baywatch star filed for the split February 26--two days after Tommy was arrested at their Malibu home. Sheriff's deputies hauled the drummer in after Pamela told them he beat her as she held the couple's seven-week-old son, Dylan, and while their 20-month-old son, Brandon, looked on.
The incident violated his probation stemming from a 1996 attack on a photographer outside an L.A. club. Lee had pleaded no contest to roughing up the paparazzo and was sentenced to 250 hours of community service, as well as anger management counseling.
He still faces a civil suit filed by the cameraman. That trial is set for April 13.
