He also has a son with Camper, 3-year-old Saint Laszlo.
The couple announced they were expecting a daughter in January and Wentz told People magazine then that he was excited given that “We have a lot of testosterone in our house.”
“I see my friends who have daughters, and it seems like a whole different kind of love that they have for each other, so I look forward to that being a completely new journey,” he said at the time. “Hopefully it’ll bring some balance to our home!”
Wentz and Camper have been together since 2011.
