Fergie gave birth to hers and husband Josh Duhamel's first child together last month, on 29 August, and after a period of relative silence from the new parents as they adjust to their dramatically different lifestyle, Fergie has been kind enough to share a photo of little Axl Jack for the first time. The Black Eyed Peas singer posted an Instagram photo of her new baby boy rocking a pair headphones on Tuesday, 17 September, after he'd passed an ear exam.

"Hearing test complete. All systems go," she captioned her Instagram snap, with her husband Josh following up her initial image with one of his own. He added on Twitter, "#paparazziyoucanleaveourhousenow."

The couple welcomed their first child together last month after spending more than three years together as husband and wife, with the couple getting married back in January 2009. Axl Jack Duhamel was born at the Cedars Sinai Medical Center in Los Angeles, the same medical center that Kim Kardashian gave birth to North West in and where NBA star Dwight Howard had his child, where he arrived right on schedule and where Fergie apparently gave birth via C-section.

Speaking with TMZ after the birth of the child, a representative for the couple revealed that Axl had been born at a healthy 7 pounds 10 ounces and arrived with no health concerns. As you may have already assumed (or known already), the name for their new child was inspired by Guns 'N' Roses frontman Axl Rose - one of the couple's joint favourite artists.
