OK! Exclusive: Mariah Carey Reveals A Sexy And Slimmer Figure And James Packer Is To Thank For It!

Mariah Carey is back and she's better, thanks to a hot new body. Find out how she lost the weight and is keeping it off with the help of her new billionaire boyfriend, James Packer!

After Mariah and Nick Cannon split last year, the diva began to look fuller, and there's a reason behind it. A source told OK! exclusively, “She wasn’t looking after herself. When she's depressed, she binges, and she was gorging on junk food.”

Fortunately, all it took was a new love from Down Under to sweep her off her feet and get her body back into tip-top shape.

“She's crazy about James and their romance is clearly good for her mind and her body," said the source. But it takes more than love to slim down. Mariah has been focusing on eating more healthy foods and even exercises with James.

“It's all about lean proteins, plenty of fruits and vegetables and healthy fats," said the insider.

"She indulges once in a while, but she's not downing fries and pizza at every turn anymore. When Mariah’s happy she can stick to a healthy diet.”
