RED HOT: Mariah Carey Flaunts Her Post-Twins Figure For JENNY Promo Event

Mariah is BACK.  And she's flaunting it all in red.  The mom of 6-month-old twins Roc & Roe hit up her first JENNY event today in NYC, as the pop icon is the weight loss company's newest spokeswoman.

Pics of her showing off her new bod today inside....

Oh...hey MiMi!  The "Fantasy" singer was on hand for the press conference as she was announced the new Jenny Craig (now called JENNY) Brand Ambassador at the Four Seasons Hotel in NYC.

And she showed off her 70 pounds slimmer bod in a spaghetti strapped maxi dress and red YSL sandals:

Gayle King was on hand for the event too.  Mariah told Us Weekly magazine in the new issue:

"I gained an enormous amount of weight. I was scared I was never going to walk again.
'I feel incredible but it was a long road,' she says. 'Being pregnant felt longer than it was. It was a huge blessing to be able to have the babies but I felt trapped in my body because I couldn't move.'
'At the beginning (after pregnancy), I was breast feeding, so I had to eat more than I normally would. It was frustrating.

Nice!  You feelin' Mrs. Cannon's new look?
