Demi Moore had a seizure Monday night before she was rushed to the hospital and is being treated for anorexia, among other substance abuse issues.
The 49-year-old Ghost star has become frighteningly thin since her split with husband Ashton Kutcher, and a source close to the actress described what happened to her.
"She collapsed after having an epileptic seizure," the source said about the frightening medical emergency.
Her dramatic weight loss has caused much speculation about her health and the source confirmed that this is one of the issues she is seeking treatment for.
"Demi is in getting treated for anorexia, as well as other issues that caused her seizure," the source said.
"She has not taken care of her health at all lately and has lost a ton of weight."
The actress is reportedly seeking help for substance abuse as well.
Demi and Ashton's six year marriage ended in 2011 after Star magazine's bombshell report that Ashton cheated on Demi with Sara Leal the weekend of their wedding anniversary.
She announced that she was separating from him but has yet to file divorce papers.
