Brooke Mueller is back in rehab for the 19th time

Brooke is back in rehab rehab again for the 19th time  -- because she now confesses she has a big problem with a powerful drug.


Brooke --who checked into rehab last night -- won't bump into any walls in the middle of the night because she knows the  facility very well -- she's been there before. She'll be living there for an undetermined period of time
