Actress Julia Roberts has given birth to twins, a boy and a girl, in a Los Angeles hospital, People magazine has reported on its website, citing an anonymous source. A magazine spokeswoman said Roberts, 37, gave birth around 3 a.m. local time (11 a.m. British time) on Sunday to Phinnaeus Walter and Hazel Patricia. A spokeswoman for the star did not return phone calls. Roberts married the twins’ father, cameraman Danny Moder, 35, in 2002 on Roberts’ ranch in Taos, New Mexico. The two had been splitting their time between homes in Taos, New York, and the Los Angeles area. The actress was hospitalised late last month after experiencing early contractions. Doctors advised her to remain on bed rest until she gave birth. Roberts, who has no other children, was married to country music star Lyle Lovett from 1993 to 1995.
