Pete Wentz is a dad again!
The Fall Out Boy bassist's model girlfriend Meagan Camper, 25, gave birth to a baby boy, Saint Lazslo, on Wednesday. While Wentz, 35, is already a father to 5-year-old son Bronx from his previous marriage to Ashlee Simpson, this marks his first child with Camper.
"Mom and baby are happy and healthy," a rep for the couple told People
. "They are thrilled at the addition to the family and Bronx is over the moon to be a big brother."
Wentz didn't find out the new baby's gender until after he was born.
"We're waiting," the new dad told People in May. "I think we'll probably do a surprise on this one."
Wentz and Camper have been together for three years.
