Fergie and Josh Duhamel have shared the first pictures of their newborn son Axl Jack Duhamel.

The Black Eyed Peas singer gave birth to her first child with her actor husband on August 29, and the couple have now revealed the first snaps of their bouncing baby boy via social media.

Josh, 40, shared the first picture of Axl on his Twitter account, which sees the baby sound asleep and wrapped up warm in a blanket and hat.

He captioned the photo, writing: "Axl Jack Duhamel Day 1. Life is good :) (sic)"

The 'Transformers' hunk also appeared to joke about the influx of photographers surrounding the couple's Los Angeles home in a bid to nab the first pictures of the newborn.

He added: "#paparazziyoucanleaveourhousenow (sic)"

While Josh chronicled his son's first day of life, mum Fergie, 38, quickly followed up with a picture of little Axl's eventful second day on earth.

The little tot is seen with what appears to be medical headphones attached to his ears in the snapshot as he undergoes a hearing test.

The 'Fergalicious' hitmaker must have breathed a sigh of relief as her son passed the exam with flying colours, ensuring he is fully equipped to one day follow in her musical footsteps.

She wrote on Twitter: "Axl Jack Duhamel. Day 2 of life. Hearing test complete. All systems go. #chillin (sic)"
