Charlie Sheen's former wife Brooke Mueller was rushed to hospital on Friday morning after an overdose, according to reports.
The previous evening she was seen looking glassy-eyed as she stepped out of a car upon her arrival for dinner at Mr Chow, the Daily Mail reported.
However, Mueller's publicist has spoken out to claim that no drugs were involved.
Instead, Steve Honig said in a statement that she was mistakenly believed to be unresponsive while sleeping.
"An assistant thought Brooke was non-responsive while she was napping and hastily called an ambulance," he 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," he added.
According to TMZ.com, the 35-year-old, who has a long history of drug abuse, was taken to a Los Angeles hospital in the late morning.
The website reports that the Los Angeles City Fire Department informed them that Brooke was transported to the hospital from her Tarzana home at 11.42am.
Sources reportedly told the website that people around Mueller are "deeply concerned" and allege that she has been taking drugs for several weeks.
But Mueller is so determined to prove she was not on drugs, she told Radar Online: "I am going back to the hospital to get the test results that will prove that I wasn't on drugs." (ANI)
