Brooke Mueller is back in rehab.
A source confirms to E! News Charlie Sheen's ex entered a treatment facility following her hospitalization in November, while her mother, Moira Fiore, is taking care of the former couple's twin sons, Max and Bob, 7.
Entertainment Tonight was the first to break the news as Mueller's sister, Sydney Wolofsky, told the publication the actress was the one who made the decision to go back for treatment and is "doing a lot better."
The news of her rehab comes one month after Mueller was given an evaluation when she went missing with a nanny and her two sons.
