It has been a year since Mariah Carey and Nick Cannon announced their divorce and since then the diva has moved on with Australian billionaire, James Packer. But has she really moved on from her ex?

A recent report said that the Mariah and James, actually, have fights as the singer still includes her ex in their conversation.

Mariah's probably not even aware of how much she talks about Nick in front of James - and James is sick of it. So he was livid when he found her watching Nick on his TV show," a source close to the Butterfly singer tipped.

And here's more. When the gaming tycoon and the singer fought, the singer "flat-out EXPLODED" in response.

The tipster disclosed that Mariah is still affected with any news she heard about her ex and may be back soon.

"Mariah keeps hearing from pals how Nick whimpers he's 'broken' over their breakup - and she's still nuts about him. NO question they'll be back together, hot and heavy!"

The rumors came amidst newly-released photos of Cannon hanging out with TLC's Rozonda "Chilli" Thomas in August following their collaboration for a music video. The rumored lovers also has some family bonding with Chilli's mom and proceeded for some cozy date night at Warwick Nightclub in L.A.

Although neither of them admitted their dating status, Cannon mentioned about their 'chemistry' in an interview. "We've got an amazing music video together. And the chemistry is undeniable. I'm telling you, it's real. I'm having fun she's having fun."

Previously, news outlets were putting the blame on the AGT host for the delayed processing of their divorce with sources saying that the he is reluctant to sign the divorce papers.

Cannon, however, denied the reports.

"I wish it was that easy where you can just sign something and say, 'Oh, I'm done,' but it's a lot of things that go with that that are beyond my control. The only thing that's important to me is my children. I want what's best for them. I believe my ex feels the exact same way," he announced in a previous interview.

Since their split, Mariah Carey and Nick Cannon reportedly remained good friends as they work together in co-parenting their twins, Morocco and Monroe.
