As TMZ first reported, a disheveled Mueller (below) left the Farmer's Daughter Hotel in L.A. Thursday at around 10:00 AM and was escorted to a sober living facility in Bev Hills.
Brooke's lawyer, Yale Galanter, told TMZ she was at the hotel to shoot something for her reality show. Galanter acknowledged a rep from the sober living facility is in the picture TMZ posted and that she went to the sober house after leaving the hotel, but says it was all part of her ongoing treatment.
Brooke went to Dan Tana's with Rick and Kathy Hilton. Kathy is one of the big wigs behind the reality show which, of course, also features daughter Paris.
