Mariah Carey puts her kids to work!

The "I Don't" singer opened up about her 5-year-old twins, Moroccan and Monroe, to ET's Kevin Frazier ahead of her All the Hits Tour with Lionel Richie -- which will kick off on March 15 in Baltimore, Maryland, and mark the first time the two chart toppers will hit the road together.

Few people work harder than Mimi, and as the pop star revealed, that's something she's passing on to her children.

"They work for me now," Carey shared, laughing, "I had to give them jobs."

"I'm trying to instill a work ethic," she explained. "I don't want them to think since they're my kids and they ... that they can just get whatever they want; do whatever they want."

Even so, Carey understands that the young children are still learning the art of chores.

"I started saying, 'OK look, guys, here's what we're going to do, you're going to help out, maybe clean a couple of things," she said. "I don’t expect it to be done properly."

And none of this is to say the siblings don't get to have fun. After all, they're already world travelers!

"I will," Carey answered when asked if she'd take her kids to Dubai. "For 5-year-old kids, they’ve traveled more than most people in their lives, and they really love it. Usually we do something like go to a children's museum."

Meanwhile, Carey also touched on her friendly ex-husband Nick Cannon's recent parting of ways with America's Got Talent.
