Ashlee Simpson-Wentz and husband Pete Wentz welcomed a son Thursday night, PEOPLE confirms.

Bronx Mowgli Wentz weighed 7 lbs., 11 oz., and was 20 1/2 inches long.

"Ashlee, Pete and baby Bronx are all healthy and happy, and thank everyone for their well wishes!"

"I would love to have a big family one day," Simpson-Wentz told PEOPLE. Added Wentz: "A big soccer team or a band!"

Congrats!!! I actually really dig the name Bronx! It's just hot - kind of like the name Beyonce - it's original and it makes ya wanna know more about someone named Bronx. Bronx's middle name sucks, (they got the name Mowgli from Jungle Book), but middle names are often unmentioned, not a big deal.

I can't wait to meet him in the People magazine spread that's inevitably on the way. People covered Ashlee's wedding and it probably has the rights to her baby pics too.
