"Two and a Half Men" is back to full capacity.

Charlie Sheen returned to the set of his hit CBS sitcom Tuesday morning and production resumed after being shut down for the past three weeks to accommodate his stint in rehab, according to a rep for Warner Bros. Television.

There are four episodes left to shoot for this season. The network has insisted the work stoppage wouldn't be noticed by viewers, because the 44-year-old actor timed his treatment to coincide with a planned two-week hiatus, thus delaying shooting by only a week, Eonline.com reports.

Sheen sought what his publicist, Stan Rosenfield, said was voluntary in-patient treatment at an undisclosed facility as a "preventive measure" to deal with his personal issues.

The newly sober Sheen was all smiles Monday when he turned up at an Aspen courthouse to plead not guilty to domestic violence charges resulting from the Christmas Day row with wife Brooke Mueller.

If convicted, he could face up to five years in state prison. However, Aspen District Attorney Arnold Mordkin said he hasn't ruled out a plea bargain in advance of the July 21 trial.

Talk show host Oprah Winfrey is expected to spend two weeks in Philadelphia defending a defamation case linked to a sex-abuse scandal at her South African girls' school.

The trial is set to start March 29.

Winfrey's lawyers say in recent filings she must attend as a named defendant and has rearranged her TV production schedule to do so. She also appears likely to testify, the Associated Press reports.

The case centers on remarks Winfrey made in suspending a headmistress amid the 2007 abuse complaints.

Winfrey had said she "lost confidence" in Nomvuyo Mzamane and was "cleaning house from top to bottom."

A judge this week refused to drop Mzamane's defamation suit.

A dorm matron was later charged with abusing six students.

Even in death, Michael Jackson is breaking new records.

The King of Pop's estate has signed the biggest recording deal in history: a $200 million guaranteed contract with Sony Music Entertainment for 10 projects over seven years, according to a person familiar with the deal.

The record-breaking contract through 2017 could be worth up to $250 million if certain conditions are met. One of the albums will be of never-before-released Jackson recordings that will come out in November, the person said.

The person spoke on condition of anonymity because the official announcement was expected later Tuesday.

Future projects also may include a video game, a DVD compilation of videos and a re-release of "Off the Wall," Jackson's fifth studio album, which first came out in 1979, accompanied by some unreleased material. Before his death in June at age 50, the pop star had wanted to reissue the album, people familiar with the deal said.

One of the projects already counted in the contract was the two-disc album that accompanied "This Is It," the film based on footage of concert rehearsals for what was to have been Jackson's comeback at London's O2 arena. Including the more than 5 million copies of that special release, Jackson has sold some 31 million albums since his death, about two-thirds of them outside the United States.

The golf star who blasted Tiger Woods after the scandal is speaking out again about Tiger's comeback at the Masters.

Jesper Parnevik scoffed at doubters, telling TMZ, "Nobody ever thought Tiger would miss the Masters. It was pretty expected."

Parnevik introduced Tiger to Elin Nordegren and is one of very few golfers to publicly blast Tiger for his affairs.

Parnevik added ... Tiger doesn't have to play a warm-up tournament before the Masters. He said, "If anyone can do it, he can," adding he thinks T.W. will do well.
