Mariah Makes History

It's no secret that Mariah loves femininity—she even has a closet filled entirely with lingerie! For the first time, Mariah allows cameras into the intimate space for a tour of her nighttime necessities. "Typically, I throw on some pj's or perhaps some boxers and a little tank and call it a day," she says. "But if we're feeling extra good about ourselves after our little diet, we might select another type of ensemble."

Mariah says many of the pieces have come from Capri, Italy, one of her favorite places to vacation. "Sometimes I'll find things there that they don't have [here], so I kind of collect lingerie," she says. "I collect perfume bottles—all things feminine."
