A week after calling reports she had re-entered rehab "ridiculous," Charlie Sheen's ex, Brooke Mueller, has indeed checked into a sober living facility, at least according to the star's lawyer.

Mueller entered rehab in Los Angeles on Friday and according to a TMZ source, was dropped off by Paris Hilton's mom, Kathy, her co-star in a new show on Oxygen.

"[She] is doing it to maintain her health," attorney Yale Galanter says.
