The couple already have their two-year-old son, Axl, and they've both been busy with Fergie working on her album and Duhamel continuing his acting career. And in an interview with On Air With Ryan Seacrest on Tuesday, Duhamel revealed if he and his wife plan to expand their family.

As it turns out, there will probably be another bun in the oven coming up shortly.

Fergie Opens Up On Possibility Of Having A Second Child

"That's the plan. That's definitely the plan," Duhamel said on the possibility of another child. "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."

The host then dished on how the actor and his son tend to match clothes and they seem to have a friendly relationship as if Axl is his dad's best buddy.

"He's like a fully functional little human being at this point," Duhamel 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."

At one point in the interview, Seacrest joked with Duhamel about his age at 43 where the actor said that having kids makes you "age quickly."

Duhamel and Fergie have been married for seven years now.
