It's always tough watching this, especially once it's elevated to this point!
We're sad to report that Brooke Mueller has once again found herself in rehab.
After a hopeful stint, Brooke went to Charlie Sheen's house one day when he noticed his ex-wife seemed REALLY out of it!
But don't think she was trying to run away from her problems! On probation for cocaine possession, she went ahead and checked herself back into treatment following the strange visit.
