Charlie Sheen’s ex-wife Brooke Mueller has checked herself into a sober living facility in Los Angeles. Brooke hasn’t relapsed back to drinking. She is taking a precautionary measure – at least that’s what her publicist is saying.

The straw that broke the camel’s back for Mueller has been the filming of her new reality show with Paris Hilton. It’s booked to go to Vegas, and Brooke says she isn’t ready to deal with Sin City just yet. It’s one thing to go out to nightclubs in LA. It’s quite another thing to cope with the all night buffet of drugs and alcohol that is Las Vegas.
