Julia Roberts, well-known for movies like Pretty Woman and Steel Magnolias, gave birth to twins Hazel Patricia Moder and Phinnaeus Walter Moder.
Roberts, who skyrocketed to fame with Pretty Woman 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 cinematographer Danny Moder in July 2002 at her home in Taos, New Mexico.
The twins are the first children for Roberts, who won the best actress Oscar in 2001 for Erin Brockovich.
