Brooke Mueller has completed her most recent rehab stint, a 45-day outpatient program, according to Radar Online. Charlie Sheen's ex-wife and mother of his two young sons, Bob and Max, entered the rehab program after an extremely public plea for help -- an extremely vulnerable scene that ended up appearing on BFF Paris Hilton and Mueller's reality show, 'The World According to Paris.'

"Brooke is just taking it a day at a time," a friend told Radar. "She has been down this road before and she knows what she has to do. Brooke needs to continue to play an active role in her sobriety. When she goes to her AA meetings everyday and talks regularly with her sponsor, she does amazing."
