Mariah Carey has broken her silence over the end of her relationship with Australian business man James Packer.

The couple ended their relationship last month, but the build-up to their planned wedding will feature in Carey’s upcoming E! docu-series ‘Mariah’s World’.

"You had a highly-publicised relationship,” DeGeneres told Carey.

“You were engaged and you were trying on wedding dresses in the docu-series. We see the behind the scenes of that, which is pretty personal. And now, you're not together anymore.”

"Now it's a whole friggin' thing," the singer replied.

"How are you, mentally?" DeGeneres asked. "Are you happy? How are you?”

"I think I'm doing well," Carey answered. "How are you?"

"I'm great," DeGeneres said. "I'm great.”

"No, I'm actually...Everything happens for a reason," Carey continued. "Things are the way they are.”

When DeGeneres brought up that Packer didn't want to appear in the docu-series, Carey answered “allegedly”.

"It's kind of difficult to talk about it at the moment," she continued.

Carey and Packer went public with their romance in June 2015 and they became engaged the following January, after the businessman proposed with a 35-carat diamond ring.

Earlier this month a source told People magazine that the signer was left feeling “hurt” after the break-up.

“First the split didn’t seem to faze Mariah. It was like she expected things to be fine soon,” a source told the magazine.

“Now she realises that things aren’t fine and not being with James makes her depressed.

“She is very hurt that he dumped her,” the source added. “She knows she will never be able to find someone like him.”
