Law enforcement sources tell TMZ ... Brooke Mueller was legally drunk when she called 911 on Charlie Sheen.
Sources say authorities gave both Charlie and Brooke blood alcohol tests. Brooke registered a .13 while Charlie registered a .04.
We're also told Brooke recanted her story to a female officer just before the bail hearing, telling the cop she was drunk when she made the 911 call. Nevertheless, law enforcement sources say police will still pursue the case -- at least for now.
We've also learned Sheen has hired well-known Colorado attorney Richard Cummins to represent him. Charlie's court date is set for February 8.
