Actress Brooke Shields (search), who turned her battle with postpartum depression into a book, is pregnant with her second child, her publicist said Thursday.

The baby is due in the spring, Alan Eichorn confirmed.

After Shields and husband Christopher Thomas Henchy gave birth to daughter Rowan Francis in 2003, Shields chronicled her post-pregnancy experiences in "Down Came the Rain: My Journey Through Postpartum Depression (search)." The book was published in May.

The "Suddenly Susan" actress said she considered swallowing a bottle of pills or jumping out the window at her lowest point. A doctor later attributed her feelings to a plunge in her estrogen and progesterone levels and prescribed the antidepressant Paxil (search).

Shields has played Roxie Hart in the long-running Broadway revival of "Chicago" since Sept. 9 and is set to continue in the role until Oct. 30. The show is in its ninth year on Broadway.

The actress scored a critical and popular success in New York last season when she stepped into the role of Ruth Sherwood in the revival of "Wonderful Town."

Shields also has appeared on Broadway as Rizzo in the revival of "Grease!" and as Sally Bowles in "Cabaret."
