It's a girl — and a boy — for actress Julia Roberts (search) and her husband, cinematographer Danny Moder (search).

Roberts gave birth to twins Hazel Patricia Moder and Phinnaeus Walter Moder on Sunday morning at a Southern California hospital, publicist Marcy Engelman said Sunday.

Roberts, 37, was confined to bed last month after experiencing a series of early contractions and wasn't due until early January. Engelman said Sunday in a phone interview that "mother and babies are doing great," but didn't release the twins' weights or other details.

Roberts, who skyrocketed to fame with "Pretty Woman" (search) in 1990, has two films coming out in early December — Mike Nichols' "Closer" and "Ocean's Twelve," the Steven Soderbergh-directed sequel to 2001's star-studded heist caper.

Roberts married Moder in July 2002 at her home in Taos, N.M. The twins are the first children for Roberts, who won the best actress Oscar in 2001 for "Erin Brockovich."
