Mariah Carey Premieres New Jenny Video

Fans already know that Mariah Carey has already lost almost all her pregnancy weight and that she's now the latest brand ambassador for Jenny, formerly known as Jenny Craig. A new promo shows just in what incredible shape she is.

Back in November this year, Mariah unveiled her post-pregnancy figure on Rosie O'Donnell's show. Also then, she announced the collaboration with Jenny, as we also reported at the time.

Often branded a diva, Mariah has made no efforts to hide the fact that she had a very difficult pregnancy, one that would often make it hard for her to stand, let alone exercise.

She gained a lot of weight and, after giving birth to twins, she found herself in a position where she had to lose all those extra pounds really quick.

This is how her collaboration with Jenny came to be. By the looks of the latest video, which comes with an updated version of her clip “You Can Make It,” it paid off.

The clip also includes other success stories from women who have tried Jenny and can vouch for its efficiency, but there's no denying all eyes are on Mariah.

It's no wonder why: she's rocking a minuscule top and a maxi skirt cut to the thigh. She's looking better than ever.

This is the second reason she agreed to become a spokesperson for Jenny, Mariah said back in November: to motivate people to do something to improve their life by overhauling their diet.

“As an artist, I use my voice to entertain. But, today I want to use my voice to draw attention to a serious matter. Two-thirds of the country is placing themselves at risk for heart disease and diabetes. Largely, that is due to unhealthy eating patterns and lack of physical activity,” she said.

“I obtained a greater understanding of this when I was pregnant with my twins and dealing with my own health issues. That's why I feel so strongly about working with Jenny and the American Heart Association to help Americans get serious about their health as it pertains to these issues which are so important,” Mariah added.
