from www.radaronline.com – The prostitute who was with Charlie Sheen when he flipped out Monday night and had to be hospitalized has told people that Sheen was using cocaine, RadarOnline.com has learned exclusively.

Charlie has been out of rehab for two months. He has battled alcoholism and an addiction to crack.

He was transported via ambulance from the Plaza hotel to a New York-area hospital Monday night after creating a disturbance.

Police say he was intoxicated.

A source close to the investigation told RadarOnline.com that it was more than that. “The prostitute says Charlie was using cocaine,” the source told RadarOnline.com.

“She said after he did the coke, he flipped out, couldn’t find his wallet and accused her of stealing it.”

Things quickly went downhill from there, with the disturbance in the room growing louder and louder.

Sheen’s representative had a different explanation for the incident and told RadarOnline.com: “What we are able to determine is that Charlie had an adverse allergic reaction to some medication and was taken to the hospital, where is expected to be released tomorrow.”

Ironically, Charlie was on a “family” vacation, spending time with ex wife Denise Richards and their children. Richards was not staying in the same room with him but a source close to the police investigation say cops did talk to her.

Richards and Sheen had hotel rooms on the same floor. She was woken up by the disturbance and spoke to authorities.

Richards went to the hospital to monitor Charlie.

A Security spokesman at The Plaza Hotel was remaining tight lipped about Charlie Sheen’s run-in at the famous establishment.

A spokesperson said: “We cannot make any comments about our guests as we respect the confidentiality of people who stay here.”

The hotel – which is a famous haunt of the rich and famous – which was formerly owned by Donald Trump before El Ad Properties bought it in 2004 for $675 million.

Sheen is on probation for a Colorado domestic violence incident with his estranged wife Brooke Mueller.
