Fergie’s Son Axl Is All Grown up in Never-Before-Seen Photos

Time flies, and Fergie is feeling it. The "Glamorous" singer honored her only child's entrance into his teenage years with a message straight from the heart.

Fergie is a proud mom. On Saturday, August 29, the longtime singer shared never-before-seen photos of her son, Axl, whom she shares with ex-husband Josh Duhamel, as she celebrated a major milestone: his 13th birthday.

Fergie took to Instagram to mark the special occasion with a sweet tribute. "13. 🎂🎂 Wow, my teenager," she began. "I'm saying that with tears in my eyes as I feel like the world is shifting beneath us. It's so beautiful to watch you grow into the kind, silly, and cool dude you are."

"You are so tough bruh 🤣🤣. Happy 13th Axl Jack. I love you," the "Glamorous" singer continued. Alongside her message was a carousel of Axl's photos spanning from his toddler years to the present day.

In the opening image, Axl looks all grown up as he leans against a brick wall, posing for the camera in a black graphic tee paired with white bottoms. He's accessorized simply with a black bracelet, with his tousled blond hair completing the look.

The next photo shows Axl as a baby, perched on Fergie's hip in what appears to be a restaurant. The carousel continues in similar fashion, bouncing between Axl's younger days, including a shot of him in a ball pit, and more recent snapshots.

One standout image shows him and Fergie dressed up for a day out, with Axl standing at a nearly identical height to the "Big Girls Don't Cry" hitmaker. And just like Fergie, Josh is also wondering where the time went.

Fergie and Josh were married from 2009 to 2019. They welcomed Axl in 2013. He is Fergie's only child, while Josh also shares daughter Rocca and son Shepard with wife Audra Mari.
