At her peak pregnancy weight, Carey, 42, was so disgusted with her physique that she refused to let even husband Nick Cannon see her unless she covered up first, she said Tuesday.
“I had a towel on in the tub,” Carey, who gave birth in April, says. “I m not lying, I promise you! You think I would let Nick see me looking rancid like that?”
The Grammy winner, who says she’s lost a total of 70 lbs. after the twins, was interviewed by Gayle King at a New York media appearance to promote Jenny diet products, for which Carey is now a spokeswoman.
