Charlie Sheen's ex-wife Brooke Mueller has completed her month long stint in rehab, according to a U.S. report.
Mueller reportedly entered a Los Angeles treatment centre earlier this year (11) to battle her longtime struggle with sobriety.
After undergoing help and recently walking free, Mueller received well wishes from pal Kathy Hilton after she missed the premiere of her daughter Paris Hilton's reality TV show, The World According to Paris, allegedly because the event was hosted in a nightclub setting.
In a post on her Twitter.com account on Tuesday (31May11), Kathy Hilton wrote, "Brooke, we r sorry u could not be with us tonight , we know your working on a bigger celebration your sobriety, we r very proud of u. XO (sic)."
Earlier that day, Mueller was snapped by X17 Online reuniting with her twins Bob and Max, who were temporarily staying at her parents' home while she completed her treatment and the boys' father, Sheen, was touring North America with his one-man comedy show.
Mueller won custody of the couple's sons before she reportedly checked into rehab.
