Lifeline Live: Celebrity Gossip & Entertainment News from Hollywood

Although some of the 10-minute conversation is bleeped, it's clear from the Demi Moore just-released 911 tape that the actress was having convulsions when friends called for an ambulance.

"She smoked something, it's not marijuana. It's similar to incense and seems to be have convulsions of some sort," a female voice tells the dispatcher.

When the dispatcher asks how old she is, the voice says, "How old is Demi? Just a sec… 49."

"Semi conscious, barely," says the caller. "She's convulsing."

When asked if the incident was intentional or accidental, the caller replies, "Intentional? She smoked something. The reaction was accidental."

And when asked if she had taken anything else, the caller says, "She's been having some issues, so I don't know what she's been taking," and adds, "I put water on her back because she's burning up. I don't know what would have caused that."

The dispatcher asks if she is responsive.

"Demi, can you hear me?" the friend says, and then tells the dispatcher, "She's squeezing me, but she can't speak."

They are told help is on the way and that they shouldn't give her anything. When the dispatcher asks if she has done this before, the reply is: "I don't know. There's been stuff recently that we're just finding out."

A male voice then takes the phone and says, "She seems to have calmed down a little bit." At that point, paramedics are at the gate.
