Fall Out Boy's Pete Wentz and Ashlee Simpson have welcomed their first child, US media reports claim.

Simpson is understood to have given birth to a baby boy – named Bronx Mowgli Wentz - in Los Angeles on Thursday (November 20th) evening.

“Ashlee, Pete and baby Bronx are all healthy and happy, and thank everyone for their well wishes,” the couple's spokesperson told People Magazine.

Wentz and Simpson met in 2006 but only confirmed their engagement at the beginning of April this year.

They exchanged vows a month later in front of approximately 150 family members and friends at Simpson’s parent’s home in San Fernando Valley.
