Mariah Carey‘s twins are two tiny stars in the making.

When the diva’s new reality show, Mariah’s World, debuts in December, the singer’s 5-year-old twins, Moroccan and Monroe, will also get some screen time.

“They can have their own show because that’s how funny they are,” the proud mom, 46, told reporters at a TCA panel promoting the E! show.

Though dad Nick Cannon has been “very supportive” of their children being featured on the show, the former couple is still figuring out “mutually” how big a role they will play.

“The truth is, they jump on the stage when they can,” says Carey. “The answer is we’re still in the process of putting everything together.”

And though they’re still toddlers, Carey says her kids have already seen more of the world than most adults.

“I try to have them do as many activities that they can that aren’t just like, the iPad,” she says. “I spend time with them. We travel together. I take them to different places. They love traveling.”

Despite her hectic schedule, however, the singer also tries to keep their schedule as “consistent” as possible — and they already take after Mom.

Says the star: “Yesterday, my son was being the deejay. Miss Monroe has a really, really good ear for music and a really beautiful tone, but I can’t force her to sing, so if she wants to sing, she’ll sing. I encourage her because it’s a great outlet.”
