Former Black Eyed Peas singer Fergie, 38, and her TV presenter husband Josh, 40 welcomed the arrival of their first child over two weeks ago but were keeping the little one under wraps.

Mummy and daddy each posted a photo on their Facebook pages, and tweeted the snaps to their fans, perhaps in a bid to rid the photographers waiting outside their home for the first baby picture.

Josh’s photo of baby Axl – taken on the first day of his life – was captioned 'Axl Jack Duhamel Day 1 #paparazziyoucanleaveourhousenow.’

New mum Fergie posted a second photo taken when Axl was just 2 days old and having what appeared to be a hearing test, with headphones on his ears wearing a cute baby beanie hat.

Protective dad Josh initially told his Twitter fans that he and his wife wouldn’t be posting any snaps any time soon, writing: ‘Right now we just want him all to ourselves.'

But luckily, the couple had a change of heart and we were treated to a sneaky peek yesterday.

Fergie has yet to make an appearance in public since Axl was born on August 29, weighing 7 lbs, 10 oz.

She gave birth via C-section at an LA hospital with her husband by her side.

It is thought the couple named their first child after Guns N’ Roses rocker Axl Rose as Fergie is said to be a big fan of the band.
