The mom of two and Paris Hilton BFF has successfully completed a 45-day outpatient program that allowed her to be with her twin boys, Bob and Max, at night, a source close to the rehabber tells E! News.
So what made Brooke head back to rehab in the first place?
Apparently, the reality star had seen episodes of The World According to Paris and didn't like the way she sounded or looked while under the influence while onscreen, reports Radar.
Mueller had entered rehab while filming the Oxygen series, and her breakdown and desire to seek help for her addictions was caught on tape.
A source told the site that althought Mueller still has temptations, she's making progress and is regularly attending AA meetings and talking with her sponsor. Her Vatican warlock assassin ex currently watches the duo's 2-year-old twins every other weekend while Brooke spends most of the time with the boys, including eight hours a day while in rehab and all day now.
"She is out. She is doing amazingly well," our source confirmed to us.
The reality star has been struggling with addiction issues for some time. She reportedly spent last Thanksgiving in a sober living facility, then checked back into a sober living house in early December.
In May, she skipped the premiere of the reality show at the Tropicana Bar in Hollywood because she didn't want to be in a nightclub atmosphere. Her mother and stepfather went in her place.
