There seems to be an exodus from Betty Ford ... because TMZ has learned Brooke Mueller has left the rehab facility for greener pastures.
Sources familiar with the situation tell TMZ ... Brooke has entered a rehab facility in Orange County. As for why she left Betty Ford ... we're told Brooke and her people felt Betty Ford was good for "detoxing" ... but she needs a different place to reboot so she can go back home and attempt to lead a clean and sober life.
It's interesting ... Betty Ford has the reputation of being the Rolls-Royce of rehab, but it seems some patients think the facility's value is limited.
We're told Brooke and her people think the O.C. facility will help her assimilate back into society -- something they didn't think Betty Ford could do.
We broke the story ... Lindsay Lohan also left Betty Ford because the judge and prosecutor, along with Lindsay, felt the program had value for 30 days, but not the full 90.
