(Cover) - EN Showbiz - Mariah Carey has made a sarcastic dig about Kim Kardashian's short-lived marriage.

The mother-of-two was unveiled as the new face of weight loss company Jenny Craig yesterday and showed off her post baby body.

But the Grammy winner had much to say about making a relationship work in the entertainment industry.

"I'm a real person, I'm not going to put on a fake face for Hollywood," Mariah said as she spoke about her marriage to husband Nick Cannon.

"Sometimes we make each other mad, that's why we aren't divorced after four months," she said derisively.

The audience at the New York event gasped at the comment knowing she was referring to Kim's infamous 72-day marriage to Kris Humphries.

Mariah apparently looked sheepish after her remark but was resolute in her belief and said, "I'm sorry, I'm just saying."

The Butterfly singer opened up about how upset she was with her body carrying her now six-month-old twins Monroe and Moroccan and wouldn't let Nick see her naked.

"I had a towel on in the tub," Mariah said. "I'm not lying, I promise you! You think I would let Nick see me looking rancid like that?"

But she says she has lost about 70lbs although she doesn't know exactly how much she weighed while pregnant because she didn't "want to feel that bad."

"I had, like, no bones for a while," she said gesturing to her collarbone. "It's important to me to feel my bones!"

Mariah also dished about her past relationships and how she found it difficult to let people into her life.

"You know, I had a situation in the past where I was controlled, and I was really young, and it affected the way I trusted people," she revealed. "I had no team, besides my dog and my cat. Me and Nick we always joke, I'm an Aries, I need so much attention!" (C) Cover Media
