The 37-year-old rapper has revealed his six-year-old twins Moroccan and Monroe - whom he has with his ex-wife Mariah Carey - have already taken a shine to being protective older siblings to their 14-month-old brother Golden, who Nick has with his former girlfriend Brittany Bell.

He said: "They love hanging out with him, and it is almost like they are more concerned about him having fun than them having fun. They are always trying to make them laugh, and he is walking now, so they are trying to get him all the toys.

"Watching that whole older sibling thing take place, they understand the responsibility of it. They understand that they can teach him things, so it is really cool."

Nick's twins turn seven on Monday (30.04.18) and the former 'America's Got Talent' host can't believe how quickly they've grown up.

Speaking to 'Entertainment Tonight', he joked: "I'm fine with my son growing up. It's my daughter that I have a problem with. I mean, shotgun's loaded."

This isn't the first time Nick has gushed over how his brood interact with one another, as he previously said it was "cool" to watch the twins look after their younger brother.

He said: "They love it. We get to spend every holiday together. Golden just took his first steps, and they were there helping him walk.

"It's cool to see 7-year-olds approaching a one-and-a-half-year-old and how they're taking on that big brother and sister role."

Nick's family life seems to be running smoothly, as it was previously claimed he and ex-wife Mariah are "fully committed" to co-parenting their children, even more than three years after the pair went their separate ways.

A source said: "They are both fully committed to being the best parents they can be to the twins. Family is Mariah and Nick's number one priority and they are such great, hands-on parents."
