The new parents, who just celebrated their fifth wedding anniversary, took their adorable son Axl Jack out to visit good friend Oliver Hudson on Sunday in Brentwood, Calif.
The handsome four-month-old lad, who is already taking after his famous dad, was dressed in a black hoodie, blue jeans and Converse sneakers.
The Black Eyed Peas singer was photographed gently cradling her baby boy to her chest, while her hubby effortlessly carried him under one arm at a different point during the day.
Last month, the singer revealed that "being a mommy is the best thing ever."
The proud mama and papa also love to share pictures of their little bundle of joy on their Facebook and Instagram accounts.
Over the holidays, Fergie shared a precious Christmas card featuring her son to spread some holiday cheer and expressed her happiness saying, "It's such a happy feeling as a parent to see the curiosity in your child's eyes."
