A report from Us Weekly early Friday claimed that Weeds star Mary-Louise Parker was set to replace Demi Moore in the upcoming biopic, Lovelace, but it's actually Sarah Jessica Parker who will step in to fill the role of feminist icon, Gloria Steinem.

Moore was forced to drop out of the film on Tuesday after being admitted to the hospital for "exhaustion," and the Sex and the City hottie has now officially signed on to play Steinem, according to the film's press release.

Lovelace is currently shooting in Los Angeles, and centers on the famous 1970s porn star, Linda Lovelace, played by Amanda Seyfried, who costars alongside James Franco, Sharon Stone, Peter Sarsgaard and Adam Brody.

Demi is currently putting her career on hold to "seek professional assistance to treat her exhaustion and improve her overall health," her rep said in a statement.
