Mariah Carey talks watching herself try on wedding dress in upcoming reality series

She brought fans inside her wedding dress fitting for her upcoming reality show, Mariah's World.

And while Mariah Carey ended up splitting from Australian billionaire James Packer before she ever walked down the aisle, the hit-maker, 46, said re-watching herself all dressed up in the gown was a 'bittersweet' moment.

The star told Entertainment Tonight's Carly Steel:  'All of those moments are bittersweet. But you just have to focus on what you're focusing on, and keep it moving.' 

The hit-maker seemed determined to do her best to move on from the split when she initially told Carly, 'You know, I could sit here and be in this whole emotional moment about it, but I'd rather say,' Mariah said, before laughing and declining to continue her train of thought.

In a trailer for the upcoming reality show Mariah's World, set to premiere on E! on December 4, Mariah can be seen surrounded by her team as she tries on a gorgeous white wedding gown.

Veil over her face, the chart-topper tells a stylist as she pointed to the top of her head, 'Just a little tiara right there. Just a little tiara.' 

The reality star is also seen talking about her plans for the wedding, as she tells the camera, 'Can you believe that I want to have endangered species at my wedding!?'

Mariah's breakup from the Australian businessman was made public last month.

The couple had reportedly split a couple of weeks after a disagreement on a trip to Mykonos in Greece. 

Since then, Mariah has been seen with her back-up dancer, Bryan Tanaka.

The hit-maker evaded directly answering whether or not they were romantically involved with each other.   

'You'll have to just wait and watch the show,' she teased. When Carly asked if there was a romance going on, Mariah added, 'Oh darling, you're just being dramatic!' 

Mariah added her ex-husband Nick Cannon, who she has five-year-old twins Monroe and Moroccan with, was 'cool' about being on the show. 

'It's more like, he was coming to see the kids anyways, so I was like, "Do you mind being on the show?"'

It had previously been reported that Mariah was claiming an 'inconvenience fee' of $50million from ex-fiance since their split. 

The songbird said every woman deserves an 'inconvenience fee' - and more - during her interview with ET.
