Fergie and Josh Duhamel make an adorable pair as they bring their son along for outside escapades.

Last Thursday, Daily Mail posted new images of the happy family as they were going for a walk in a Santa Monica park. On a sunny day out, Fergie wore a grey shirt with jean shorts and a round hat while her husband sported a dark shirt with matching pants and a cap.

The couple's two-year-old son, Axl, wore a black shirt with shorts and a green scarf around his neck that showed a bit of his grungy style.

There's a good chance that the family will be joined by another member someday. Duhamel opened up with On Air With Ryan Seacrest on how he and his wife would be happy to have another child.

"That's the plan. That's definitely the plan," the actor said. "She's about to get real busy here with this album coming out next month so I'm guessing after all of that's done, we can start working on it again? I don't know."

Duhamel then dished on how it can be a challenge to care for a child at Axl's current age.

"He's like a fully functional little human being at this point," the 43-year-old noted. "Now it's just a matter of keeping him between the rails. He's a good boy, thank god, but you know, he's two-and-a-half, they like to test you as much as they can."
