Tom Sizemore (search) was ordered Thursday to remain in a live-in drug rehabilitation program for another 30 days, but he can leave to work and attend charity events.

"This next month should prove to us that you're going to stay sober — clean and sober — and work at the same time," Superior Court Judge Paula Adele Mabrey said.

Sizemore, whose films include "Saving Private Ryan" and "Black Hawk Down," has been living at Las Encinas treatment center in Pasadena for 72 days.

Based on a report from his doctor, it appears that "Mr. Sizemore has taken his treatment seriously," the judge said.

Sizemore's 6-week-old twin boys and their mother, Janelle McIntire, attended the hearing.

"I'm very, very proud to be a father," the 43-year-old actor said outside court. "I just want to put this very difficult time behind me ... I just want to live a healthy, long life and be a good dad."

One of Sizemore's lawyers, Michael Rovell, asked the judge to allow the actor to leave the treatment center with a "sober companion" on occasion. The judge agreed but said Sizemore must have an immediate drug test each time he returns.

Another hearing was set for Oct. 17.

Sizemore originally was ordered into drug treatment after pleading guilty last October to possession of methamphetamine. In July, he acknowledged a series of probation violations from that case, including using a prosthetic device to fake a drug test.

Separately, Sizemore was convicted in 2003 of domestic violence involving his ex-girlfriend, former Hollywood madam Heidi Fleiss (search).

He was sentenced in March to 17 months in jail and more than four months in drug treatment for repeatedly failing drug tests while on probation. The actor remains free on bail pending his appeal in that case.
