Josh Duhamel always wanted to be a father and six months ago when Axl Jack was born in August, his dream became a reality.
"I did it!, I did it!" he told ABC News. "I get to be a dad!"
Duhamel said he and wife Fergie's son is just "growing like crazy" and already wants his freedom.
"He's got this little car that was given to us as a gift, like a little walker, like a little Ferrrari," he said. "He loves that thing because I guess it's some sort of independence that he has, he just cruises around the house and explores."
The "Safe Haven" star, 41, said Axl Jack is rolling around and about to start crawling.
"He's eating real foods, he's holding his own bottle," he added. "All those things that are boring if you don't have a kid, but if you have a kid, it's like 'Wow, he's a genius!'"
