Julia Roberts has given birth to a boy and a girl more than a month early in a Southern California hospital.

Hazel Patricia Moder and Phinnaeus Walter Moder entered the world in the early hours of Sunday morning - and both are said to be healthy.

Roberts, 37, was confined to bed last month after experiencing a series of early contractions and wasn't due until early January.

Her publicist Marcy Engelman said "mother and babies are doing great," but didn't release the twins' weights or other details.

Roberts, who skyrocketed to fame with "Pretty Woman" in 1990, has two films coming out in nxt month - Mike Nichols' "Closer" and "Ocean's Twelve," the Steven Soderbergh-directed sequel to 2001's 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."
