While Charlie Sheen has caused plenty of controversy over the last year, it's his ex-wife and mother of their twins who is making headlines now. Brooke Mueller is back in rehab, according to sources.
There were reports earlier in the week that she was planning to go to Mexico to undergo treatment using a new drug that stops cravings. She attempted to board flights out of LAX twice last week but got into an argument with a flight attendant the first time, then did not have her passport the second time. A source says, "This was a very big step for Brooke to take. She has resisted entering a residential facility because she didn't want to be away from her sons." Brooke has been in an out of rehab so many times that friends really hope this will be her final stint.
