The Black Eyed Peas songstress was busy on set shooting stunning new images for her latest Avon campaign on Wednesday and decided to take her five-month-old son along with her.
She posted the picture on Instagram and wrote: "Mama got to hang with her lil homie today on the set of her #avonoutspoken shoot. #lilhomie."
Wearing a gorgeous short red dress covered in sequins and a pair of killer black and white heels, Fergie looked picture perfect for the camera.
However, her shot wasn't complete without a guest appearance from her adorable little boy, who she scooped up for a quick photo.
Gazing adoringly at Axl, the 38-year-old singer looked every inch the yummy mummy with her eye-catching red lipstick and windswept hair.
Meanwhile, her son was dressed just as stylishly in a grey hoody, a pair of jeans and even a tiny flat cap Aww!
Fergie gave birth to Axl last August and she and husband Josh Duhamel have been besotted ever since, frequently posting snaps online of themselves with their first born.
And now the proud parents will be able to organise play dates with another new addition to the family, as Fergie's sister Dana recently gave birth to her own bundle of joy.
Dana announced that she was also expecting last July and has now welcomed a baby son into the world called Jagger.
No doubt he and Axl will be getting up to all sorts of mischief growing up together!
Fergie tweeted over the weekend: "HUGE congrats 2 my lil sis 4 bringing Jagger into the world! Axl can't wait 2 play w/ his cousin!!"
