Charlie Sheen's ex-wife Brooke Mueller was rushed to hospital this morning after a suspected OD, TMZ reports.

Friends have allegedly been saying for weeks that they have been concerned about Brooke's current relationship with drugs, thinking that she was 'abusing' them. According to the L.A. City Fire Department she was taken to hospital at 11:42am. Despite TMZ saying that her hospital visit is due to an OD, a rep for the socialite told Celebuzz that's not the case. "An assistant thought Brooke was non-responsive while she was napping and hastily called an ambulance." The rep said, "As a precaution, Brooke was brought to a local hospital and discharged after an hour. She was diagnosed with exhaustion and dehydration and is now fine and resting at home. That's it." 

Brooke's mother also assured the website that she did not take an overdose, saying: "Brooke is fine and she is now resting at home. It definitely was not any overdose or anything like that."  

Muella has had 15 stints in rehab and has a long term drug problem. She also has twin boys, fathered by Sheen. She and her ex husband broke up during Sheen's breakdown during 2010. At the time she feared that he was 'insane', People reported at the time. Her accusations against him seem somewhat hypocritical since her more recent struggles with drug addiction.
