Pete Wentz‘s new baby is a Saint!
The Fall Out Boy bassist, 35, and model girlfriend Meagan Camper, 25, welcomed a son, Saint Lazslo, on Wednesday, Aug. 20 in Los Angeles, his rep confirms to PEOPLE.
“Mom and baby are happy and healthy,” the rep says. “They are thrilled at the addition to the family and Bronx is over the moon to be a big brother.”
Up until the baby’s arrival, Wentz — whose 5½-year-old son is from his previous marriage to Ashlee Simpson — didn’t know the sex of his second child.
