DEMI MOORE was rushed to the hospital Monday night. Her rep blamed STRESS and EXHAUSTION.
--Here's the official statement . . . quote, "Because of the stresses in her life right now, Demi has chosen to seek professional assistance to treat her exhaustion and improve her overall health.
--"She looks forward to getting well and is grateful for the support of her family and friends."
--But TMZ says there was more to it than that. They claim 911 was called to Demi's home Monday night at 10:45 due to SUBSTANCE ABUSE . . . and that's what she's seeking treatment for.
--A source told E! Online that it was a female friend of Demi's who called 911. She told the operator Demi was shaking and, quote, "acting like she was suffering from a seizure."
--Demi split from husband ASHTON KUTCHER back in November because of his alleged cheating. She's been spending most of her time since then NOT EATING.
--Due to her hospitalization, Demi has dropped out of "Lovelace" . . . the movie about legendary porno star LINDA LOVELACE. Demi was going to play feminist icon GLORIA STEINEM. (--Amanda Seyfried is playing Lovelace.)
(--Meanwhile, there are reports that Demi has her cougar claws poised to snag a Canadian rapper named RICKY J. He hit the Canadian charts in 2001 with a song called "No Means No". In 2010, he charted with a song called "Whatta Night".)
(--So what's ASHTON KUTCHER doing while Demi is struggling? He's having a blast on the rain-soaked streets of Sao Paulo, Brazil. Check out some pics here.)
