Demi Moore was "devastated" to lose her role in Lovelace.

The Hollywood actress - who has been replaced by Sarah Jessica Parker in the role of feminist Gloria Steinem in the movie about real-life porn actress Linda Lovelace - is said to have cited a "personal crisis" as to why she pulled out of the movie appearance after being hospitalized last week, according to the film's producers.

Heidi Jo Markel - who is producing the motion picture with Jim Young and Laura Rister - told People, "It was a shock and a concern for all of us. We got a call from [Moore's representative] on Tuesday morning and said, 'There's been a personal crisis and we need to let you know that.' And we were clueless. We had no idea what it entailed. We just knew she was out, that there was probably a health concern, and to move on."

Demi was rushed to the Sherman Oaks Hospital last Monday evening where she was treated for exhaustion after suffering a seizure at a birthday party she was hosting at her home. But her director friend Patty Jenkins says the brunette beauty is now recovering: "I just saw her and she's doing great. I think she's doing much better than it's made out to be. Demi is awesome and so strong. I also hate when people make it a bigger drama than what is going on. She's great."
