Ashlee Simpson-Wentz, Pete Wentz have baby boy

Ashlee Simpson-Wentz and Pete Wentz are the proud parents of a baby boy, and they're celebrating with some Bronx cheer.

Their representative says the pop and rock star couple have named their son Bronx Mowgli. The baby, born Thursday night, weighed 7 pounds, 11 ounces.

Bronx is the first child for Simpson-Wentz, best known for the hit "Pieces of Me," and Wentz, bassist for the platinum rock band Fall Out Boy. They were married earlier this year.

Their representative said in a statement: "Ashlee, Pete and baby Bronx are all healthy and happy, and thank everyone for their well wishes!"
