Ashlee Simpson and Pete Wentz welcome their first child together into the world.

The 24-year-old singer - who married Pete, 29, in May - gave birth to 7lb 11oz son Bronx Mowgli at Los Angeles' Cedars-Sinai Medical Center, a representative for the couple has confirmed.

The spokesperson said: "Ashlee, Pete and baby Bronx are all healthy and happy, and thank everyone for their well wishes."

The baby was 20-and-a-half-inches long at birth.

Fall Out Boy rocker Pete recently revealed he had been getting parenting advice from Joel Madden, who has a nine-month-old daughter Harlow with his partner Nicole Richie.

He said: "Joel gives me advice. It has been really awesome for me to go to another person my age."
