Brooke Mueller Headed Back to Rehab

Sources tell TMZ Brooke Mueller has fallen off the wagon again and she is telling people she's checking into a rehab facility for 30 days.

Sources say Brooke has been receiving ongoing treatment for substance abuse at her home, but it has not prevented her from slipping, and the signs have been noticeable for those who have recently come in contact with her.

Brooke has been in rehab multiple times for drug and alcohol abuse.

UPDATE:  Brooke's rep, Elliot Mintz, tells TMZ, "What we are really talking about is not rehab ... Brooke is receiving professional help in the area of stress management."

Mintz adds, "She recognized that it would be in her best interest to deal with personal issues involving stress that have the potential for challenging her sobriety.  By seeking proper guidance, she will be able to continue to resist returning to old behavior patterns."
