She has already hit the stage at nearly 50 concerts during her #1 to Infinity Las Vegas Residency show at The Colosseum.

And Mariah Carey revealed her secret to maintaining her phenomenal physique which she flaunts in skimpy ensembles for her sold out shows in Sin City.

'All you eat is Norwegian salmon and capers every day. That's it,' the 46-year-old pop diva admitted. 'It's the worst.'

'It's really hard. I try... my diet, you would hate it,' the All I Want for Christmas singer told E! News.

'I'm actually serious. But, no, I eat -  I try to stick with the proteins and blah, blah, blah. It's the worst.'

But Mariah split from the Australian businessman which was made public last month.

They had reportedly broken up a couple of weeks after a disagreement on a trip to Mykonos in Greece. The couple began dating in June 2015 and James proposed this past January with a $7million 35-carat engagement ring. In April a friend revealed exclusively to Daily Mail Online that the performer was determined to lose 20lbs before her big day and stuck to a strict diet.

'Mariah is only eating four ounces of grilled chicken, lean beef or one of her favorites, broiled Chilean Sea Bass or grilled shrimp with grilled asparagus,' told the family friend.  The source continued: 'She is also eating some of her favorites like baked salmon, chicken salad - with light mayo or mustard - and sushi.'
