Josh Duhamel eager for baby number two

Josh Duhamel is already eyeing baby number two after becoming besotted with his firstborn son Axl.

The Transformers hunk and his pop star wife Fergie welcomed the tot at the end of August (13), and despite the massive change to their lives, Duhamel admits he can't wait to add to their brood.

He tells Access Hollywood, "It's the best thing ever. It's the best thing that's ever happened to me. It's fantastic.

"He's a really good little baby, which means the second one will be a holy terror! Yeah, we've gotta move fast (to have another one)."

Gushing about his son last month (Sep13), the proud dad said, "We can't stop staring at him. He's our little man, we made him together. There's something you can't really describe until you go through it. I think any parents out there would understand that... It's just an incredible time for both of us."
