Nick Cannon couldn't be happier that his ex-wife, Mariah Carey, has moved on in her love life -- but admits that he's "not ready" to get back out there just yet.

Ellen DeGeneres couldn't believe it when the "America's Got Talent" host revealed that he wasn't seeing anyone.

"I wouldn't say dating. I mean I have friends and we hang out, but I'm not ready to do anything seriously," he explained. "Especially because I'm really trying to make sure I can establish being in my kids life and working. I'm always so busy. So if I'm not working, they're my number one priority."

Not letting it go, DeGeneres asked if Cannon was at least getting "booty calls."

"No, I'm being celibate I'm trying to work on myself," the "Chi-Raq" star revealed. "No sex right now."

Cannon means it when he says all his time goes to his 4-year-old twins, Moroccan and Monroe. The 35-year-old even spent Thanksgiving with Carey and the kids. "Yeah it's family. That's a family time and we'll always be family," he said. "We make the kids the number one priority, for them to see their parents together and for everybody to get along and have a great time."

He added, "It's all about unconditional love. ...They know mommy and daddy still love each other but, more importantly, they love us."

Carey, 45, is currently dating billionaire James Packer, and Cannon says he plans on meeting his ex's new guy. "I think that would be cool," he said. "We've all talked about it and it seems like it's cool."

ET spoke with Carey just after she made her red carpet debut with Packer. "I don't think either one of us thought, 'Here we are, making a debut.' He's not that guy," Carey dished to ET. "It was a lot for him. ... I just automatically pose. I can't help it!"
