First up, TMZ is claiming the 49-year-old inhaled a 'dangerous amount' of nitrous oxide, also known as a 'whip'-it', before lapsing into a seizure. According to the site, whip-it is 'not a common drug among people of Demi's age and status', and is typically used by people looking for a 'cheap thrill.'
RadarOnline agrees with the 'seizure' story, but claims Demi actually had an epileptic fit before being rushed to the hospital.
The site also claims that she's addicted to the prescription drug Adderall, which is typically used in the treatment for ADHD.
A source told Radar that the actress, who split from husband Ashton Kutcher in November, has been addicted to the drug for "about a year".
The source also said Demi's suffering from anorexia- "she literally refuses to eat any food" - and is addicted to energy drinks.
Demi's rep had nothing more to add to her original statement made on Wednesday, which you can check out here.
