Nick Cannon's twins ''love'' being big siblings to their baby brother.

The 37-year-old rapper has son Moroccan and daughter Monroe, seven, with his ex-wife Mariah Carey, and has said that since his youngest son Golden - whom he has from a relationship with Brittany Bell - was born 13 months ago, the twins have loved being protective older siblings.

Speaking to People Now, Nick 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.''

It comes after it was recently claimed that Nick and 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.''

And despite no longer being together, Mariah and Nick are ''in a really good place together right now.''

The source added: ''They call and text pretty frequently about the kids and it's always direct. They don't go through nannies or assistants.''

Meanwhile, Nick previously spoke about his ''unconditional love'' for the 'We Belong Together' hitmaker, whom divorced in 2016.

He said: ''It's funny when they say 'co-parenting' - that phrase is a little redundant. You can't co-parent, you have to parent, and that's what we do well because when it comes to our children, we're selfless individuals - they're first.

''You're reminded that it's all about unconditional love and they've got to understand that to its core. Whenever we can show that - even if we're not together, [that] we love each other unconditionally - and become that fine example to our children, they'll grow up to be good human beings, hopefully.''
