It’s a boy for Maya Rudolph.
The Bridesmaids star, 38, and director Paul Thomas Anderson welcomed their third child, son Jack, on July 3, her rep tells PEOPLE.
Jack – who is home and doing great – joins big sisters Pearl, 5½, and Lucille, 20 months.
While pregnant, Rudolph said she was especially excited to discover the sex of the baby, which she and Anderson chose not to find out prior to the delivery.
