Pete Wentz has become a father again.
The Fall Out Boy bass player, 35, and his girlfriend Meagan Camper welcomed a baby boy - their first child together - into the world on Wednesday (20.08.14) in Los Angeles and have named him Saint Lazslo.
A representative for the couple told PEOPLE.com: "Mom and baby are happy and healthy."
The couple are overjoyed with their new bundle of joy and Pete's five-year-old son Bronx Mowgli, with whom he has with his ex-wife Ashlee Simpson, has fallen in love with his new baby half-brother.
The representative added: "They are thrilled at the addition to the family and Bronx is over the moon to be a big brother."
Meanwhile, the loved-up pair were keen to keep their baby's sex a surprise throughout the pregnancy and wait until the tiny tot had arrived into the world.
Pete said previously: "I don't know yet [whether the baby is a boy or a girl], [but] I think we'll probably do a surprise on this one."
The hunk and his model beau, who have been dating since September 2011, announced they were expecting a baby together in February by posting a picture on Instagram of them kissing and Pete touching Meagan's stomach.
He accompanied the snap with the caption: "We're super excited to announce we're expecting a baby!"
