Josh shared this photo (below) of baby Axl on his Instagram account on Tuesday, with: "Axl Jack Duhamel Day 1 Life is good :)#paparazziyoucanleaveourhousenow"
Meanwhile, Fergie released a photo of her young son wearing a set of headphones (could he be listening to the Black Eyed Peas?), with the caption: "Axl Jack Duhamel. Day 2 of life. Hearing test complete. All systems go. #chillin"
Named after Guns 'n Roses rocker Axl Rose, the little guy was born on August 29 via c-section in Los Angeles and weighed at 7 lbs. 10 oz.
Congratulations to the happy couple and their adorable new baby!
