The couple welcomed Saint Lazslo (the baby, of course, not the actual saint) on August 20 in Los Angeles, and both baby and mom are happy and healthy, a rep told People.com. This is the first child for the couple; Wentz has a 5 1/2-year-old son, Bronx Mowgli, with former wife Ashlee Simpson.
Wentz joins two other Hollywood dads who announced births this week. Carson Daly welcomed daughter London Rose and Foo Fighters' Dave Grohl welcomed daughter Ophelia Saint. (So maybe Saint is a rock and roll thing?)
Wentz and Camper reportedly waited until the birth to find out the baby's gender, though I'm guessing they cooked up the quirky name well beforehand. They've made no secret about wanting to start a family together, and it sounds like they're more than prepared for their newest addition. "What's more exciting than having the pitter-patter of another little gremlin running around?" Wentz said earlier this summer. "Now it will be two-on-two."
Congratulations to the new family!
