Nelly and Ashanti's son KK is already "walking" and "terrorising"

Speaking to Extra, he smiled: "He's terrorising. He's walking. He thinks he's such a big boy...

"He just loves pushing everything... He takes the luggage, and he just wants to push it with the wheels."

Nelly - who already had children Shawn, Chanelle, Sydney and Cornell before he and Ashanti had KK together - also revealed he's excited for the festive season.

He added: "Been in this business for a long time, so a lot of the holidays we haven't been together as much as we would love to, but now, you know, since I do have, so to speak, my own family now, we try to make sure that that's not an issue."

Meanwhile, Ashanti previously admitted the couple each have very different approaches to parenting.

She told PEOPLE magazine: "For me, obviously this is my first child.

"We have to boil everything and sanitise everything. Everything has to be organic. His sheets are organic, his socks, food-grade silicone, everything. I'm just very, very protective."

Nelly said: "I think I understand a little bit more about children. They learn more on their own."

The Hot in Herre hitmaker thinks Ashanti is "motherly overprotective" but he is more "safety overprotective" and insisted it is important for parents not to do everything for their children.

He said: "I know if they don't learn certain things by the time they reach a certain age, we're going to pay for that, I promise you. And it's going to backfire on us in a big way."

He jokingly added: "Right now I know she's loving it, but that boy turns 17 or 18, she going to be like, 'Why is he acting like this?' And I'm going to ask [Ashanti's mom and manager, Tina Douglas] for that video of him being three. And I'm going to say, 'You see this right here when he used to...'"
