UPDATE: Demi Moore in Treatment for Anorexia & Substance Abuse After Reportedly Having a Seizure

It has been confirmed that Demi Moore was hospitalized Monday night for substance abuse, but now, new reports say the actress had a seizure before being rushed to a treatment facility for anorexia and exhaustion. 

Sadly, Demi has become extremely thin since filing for divorce from her husband of six years, Ashton Kutcher, who allegedly cheated on her with a much younger woman. A source close to the actress tells RadarOnline.com that her personal struggles not only deal with drug abuse but also an eating disorder.
