Ashlee Simpson-Wentz and husband Pete Wentz welcomed the arrival of their first son on Thursday night.

Bronx Mowgli Wentz weighed in at 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!” a spokesperson tells PEOPLE.

The Bronx is per capita the poorest of New York City’s famous five boroughs. Mowgli was the name of the kid in The Jungle Book. What do you think of the name Pete and Ashlee have selected for their baby boy?
