Charlie Sheen Brooke MuellerBrooke Mueller, who will soon be divorced from Charlie Sheen, is said to be moving back in with the 'Two and a Half Men' star, RadarOnline.com reports.

"She moved in several days ago," an insider tells Radar. Sheen and Mueller separated on Christmas Day 2009 after an altercation that led to assault charges against the actor. Sheen filed for divorce last November, citing irreconcilable differences.

A second source confirms the rumor to Radar, adding that Mueller has been at Sheen's home since Saturday, along with the couple's twins, Bob and Max, and several nannies.

What about recent reports that Sheen is "in love" with a new girlfriend who he's been seen on set with? "He is not committed to one woman right now," RadarOnline founder and executive vice president David Perel tells PopEater. "His definition of 'girlfriend' is different than ours."
