Mariah Carey appears to be well and truly putting her heartbreak behind her as she throws herself into work.

The newly single diva hit the stage in China as part of her Elusive Chanteuse World Tour in an astonishingly skimpy outfit – so skimpy she gave the audience a full flash of her undies.

The 44-year-old beauty seemed totally oblivious to the fashion fail while she warbled away and her backing dancers jumped around stage behind her.

At one point the Butterfly singer was even carried around on a red velvet cushion before strutting her stuff up and down the stage in Beijing.

And not just content with showing off her undies, the top half of the jewel-encrusted outfit also left little to the imagination.

Though later on she did slip into a less flesh revealing black floor-length black dress.

Mariah took to the stage a week ago in Tokyo, as she kicked off her Elusive Chanteuse World Tour, but not everyone loved it.

A video, taken during the show and obtained by TMZ, appears to show the star struggling – see that above.

“It’s a wrap for Mariah Carey’s singing career,” one fan wrote, while another added: “Mariah Carey should”e bowed out right when her voice was giving out. Save herself the embarrassment.”Casually being carried around ( Image: Imaginechina/REX)

Meanwhile, Mariah’s ex Nick has been spotted on a dinner date with a stunning mystery girl.

The father-of-two was pictured suited and booted on a night out with a super-tall beauty on Thursday night.

Nick and his mystery lady were spotted in Tribeca, New York where they headed to a fancy restaurant – just the two of them.

The presenter wore a dark blue three-piece suit for his night out, with a red shirt and silk tie while his date for the evening wore a comfy blush jumper, leggings which showed off her endless pins and sky-high platforms.
