Brooke Shields, who is pregnant with her second child, says of her baby due in May: "It's a girl!"

"I wasn't sure I was going to make this public," Shields told People magazine in a report Tuesday. "I'm thrilled for my daughter to have a little friend. Two Tauruses, it's a huge trick being played on me."

Shields' other daughter, Rowan, who is 2, was born in May.

The 40-year-old actress has been married to TV writer-producer Chris Henchy since 2001.

Shields chronicled her post-pregnancy experiences in a memoir, "Down Came the Rain: My Journey Through Postpartum Depression." Her outspoken support of antidepressants prompted criticism from Tom Cruise, a Scientologist who opposes psychiatry and prescription medication to battle depression.

The actress, who began modeling as a toddler, has appeared in films including "Pretty Baby," "The Blue Lagoon" and "Endless Love." Her TV sitcom, "Suddenly Susan," ran from 1996 to 2000.
