Pete Wentz and his model girlfriend of three years Meagan Camper welcomed a baby boy named Saint Lazslo on Wednesday.

“Mom and baby are happy and healthy,” a rep for Wentz told People. “They are thrilled at the addition to the family and Bronx is over the moon to be a big brother.”

Wentz is already dad to Bronx Mowgli, his 5-year-old son from his previous marriage to Ashlee Simpson.

Saint is the latest Hollywood baby to be given an unusual moniker.

Earlier this summer, Christina Aguilera named her new daughter Summer Rain, Lil Kim welcomed daughter Royal Reign and Ciara named her son Future.
