from www.mtv.com – Amidst her personal woes, Demi Moore, who had been set to play Gloria Steinem in the Linda Lovelace biopic, has been replaced by “Weeds” star Mary-Louise Parker.

Sources confirm to UsMagazine.com that the TV star will fill in for Moore, who had to drop out of the film earlier this week after she was hospitalized for “exhaustion.”

On Thursday, there was speculation that Chloë Sevigny would play the feminist icon when she was cast as a feminist journalist, but now it seems that those are two different roles.

“Lovelace” is currently shooting in Los Angeles with Amanda Seyfried playing the film’s central character, ’70s porn actress Linda Lovelace.

As the Demi drama rolls on, there are reports that Madonna reached out to the actress shortly after she was hospitalized. Moore has since been released from the L.A.-area hospital.

Sources tells E! News that the singer called her actress pal. “Madonna told Demi she was there if she needs anything,” the E! source says, adding, “They’re pretty tight.”

The ladies last hung out during Golden Globes weekend, and they reportedly were going to see one another again over Super Bowl weekend; Madge is slated to perform during the halftime show. The status of their annual post-Oscars bash is currently up in the air.

While speculation runs rampant about why Moore was hospitalized, sources say that her ex, Ashton Kutcher, is “deeply concerned” for her. Moore is rumored to have been doing nitrous oxide before landing in the hospital. “He still cares about her and wants the best for her,” the source added. “But their marriage is ending and they are both moving on with their lives.”
