The Linda Lovelace biopic has a new Gloria Steinem.

Sarah Jessica Parker will replace Demi Moore as the feminist author and activist.

Moore, 49, dropped out of Lovelace, starring Amanda Seyfried as the '70s porn star, after Moore was hospitalized this week.

A 911 caller reported the actress had gone into convulsions after she "smoked something." Moore is now seeking "professional assistance to treat her exhaustion and improve her overall health," he rep says.

Filming began last month in Los Angeles.
