LOS ANGELES, California, United States?Actor Charlie Sheen pleaded guilty to an assault charge arising from a violent Christmas Day altercation with his wife but avoided jail under a deal with prosecutors, his lawyer said Monday.

Although Sheen, 44, was sentenced to 30 days in jail following his guilty plea at a court in Aspen, Colorado, the star of "Two and a Half Men" will not spend any time behind bars.

Instead Sheen will undergo 30 days of treatment at the exclusive Promises rehabilitation center in Malibu near the actor's California home.

However the TMZ.com entertainment website reported that because Sheen had already spent more than one month at the facility earlier this year, the actor would face only a "few seconds" at the center.

Sheen will also spend 30 days on probation and undergo 36 hours of anger management counseling.

Sheen's attorney Yale Galanter told reporters Sheen would be back at work on the set of "Two and a Half Men" on Tuesday. "He's anxious to get the sentence over with and complete his probation," Galanter said.

Sheen was arrested on December 25 in Aspen on charges he threatened wife Brooke Mueller during an argument at a rented holiday home.

After several entanglements with the law in the 1990s in cases related to drugs, domestic violence, and prostitution, Sheen is now one of the best-paid TV comedians thanks to "Two and a Half Men" and "Spin City."

In 1997, the actor was tried for attacking his girlfriend at his California home. He has also been accused of assaulting his ex-wife actress Denise Richards, a former James Bond girl.
