Black Eyed Peas singer Fergie gave birth to the couple's first child at a Los Angeles area hospital on 29 August, and now the proud parents have introduced him to the world.
Fergie posted a picture of the adorable infant at two days old to Instagram on Tuesday (17 September). She added the caption: "Axl Jack Duhamel. Day 2 of life. Hearing test complete. All systems go. #chillin."
Josh shared a separate photo on his own Facebook page, taken when Axl was just a day old. He wrote: "Axl Jack Duhamel Day 1. Life is good."
Transformers star Josh also added the hashtag, "#paparazziyoucanleaveourhousenow", suggesting the couple released the pictures to appease the media and public interest.
Just yesterday, a fan queried Josh on Twitter about when they'd see a photo of the newborn, with Josh responding: "Right now we just want him all to ourselves."
Fergie and Josh announced the pregnancy back in February, with Josh then confirming in July that they were expecting a baby boy.
The couple have been keeping a low profile since becoming parents. Fergie's most recent public appearance was on 20 August, when she supported Josh at a screening of his new movie Scenic Route in Los Angeles.
Rocking leather and studs, the 'London Bridge' singer jokingly referred to herself as "rocker mummy".
