Charlie Sheen is furious that his ex-wife Brooke Mueller has moved out of her female-only sober living facility.

The 35-year-old socialite, who has temporarily lost custody of their four-year-old twin sons, Max and Bob, has rented a new beach house in San Clemente in Orange County, California, so that her boyfriend of one year, Jaron Lowenstein, can visit her.

Brooke, whose sons are currently in Denise Richards' care, originally moved into the plush sober living house in San Juan Capistrano, close to her new residence, after leaving the Betty Ford Clinic because she was unhappy about being made to do chores there, and Charlie is allegedly furious she has moved again.

A source close to the 'Anger Management' star told gossip website RadarOnline.com: ''This is extremely distressing because Brooke's actions show she just isn't taking rehab seriously.

''Her approach to treatment is very unorthodox to say the least. What is very bothersome is that the facility is allowing Brooke to do this.

''There is no indication that Brooke is being drug tested as required when living in the sober living facility. Brooke knows that custody of her boys is on the line, yet she moved out of the sober living house so that her boyfriend could visit. Brooke said she was a celebrity and couldn't have any privacy at the sober living facility.''

The insider indicated that Charlie decided to ask a judge to reduce Brooke's monthly child support payment after he found out she had moved out.

The source explained: ''After Charlie found out that Brooke bailed on the sober living facility is when he asked his attorney to draw up the papers to reduce the child support. He didn't want to do this, but Charlie didn't want to be contributing to her drug habit because the child support is Brooke's only source of income.''
