Brooke Mueller has had a change of heart ... and has checked herself in to a full-time rehab center ... TMZ has learned.
Mueller's rep, Steve Honig, tells TMZ, "After further reflection and consideration, Brooke has decided to remove herself from the media spotlight and has entered a long-term in-patient treatment center where she can focus on her recovery without distraction."
"She has already arrived at the facility and, out of respect for her privacy, no further information will be released about her treatment. Brooke’s goal is to maintain her sobriety and she believes this is the best option to reach that goal."
“Brooke will retain custody of the children, who will remain in their home and familiar surroundings and be under the care of their longtime nanny. Charlie and Brooke’s parents fully support her decision and everyone recognizes the importance of maintaining the children's normal routine."
