Pop singer Ashlee Simpson has given birth to a baby boy, People magazine has reported.
Bronx Mowgli Wentz was born on Thursday night weighing 7lbs 11oz (3.5kg) and was 20.5 inches long.
"Ashlee, Pete and baby Bronx are all healthy and happy, and thank everyone for their well wishes!" a spokesperson told People.
It is the first child for the 24-year-old and her husband, Fall Out Boy's Pete Wentz, who married in May.
The pair announced the singer's pregnancy a few weeks after their Alice In Wonderland-themed wedding at Simpson's family home in California.
"I would love to have a big family one day," Simpson told People at the time.
Wentz had dismissed rumours of the pregnancy as "crazy" a month earlier.
The couple have been together since 2006.
They are having a joke with that name, surely
Poor kid.
