Julia Roberts Welcomes a Baby Boy

Julia Roberts has welcomed her third child, a boy named Henry Daniel Moder.

Henry was born Monday in Los Angeles and weighed 8½ lbs. “The Moder family is doing great,” Roberts’s rep, Marcy Engelman, tells PEOPLE exclusively.

Roberts, 39, and husband Danny Moder, 38, are already parents to twins Hazel and Phinnaeus, who turned 2 in November.

The actress confirmed in December that she was expecting baby No. 3.
