Mariah Carey Bares Her Midriff in Chilly NYC

Mariah Carey showed off her stomach when she strolled through NYC yesterday in a crop top and maxi skirt. During the afternoon, Mariah told her followers on Twitter that she would have to skip watching last night's episode of American Idol because of her work schedule. She wrote, "Watching American Idol? I'll have to catch it later, grandiosity in the works! Pon de set." Mariah didn't reveal what she was shooting, but her tummy-baring outfit may have been involved since, while it was warmer than usual in NYC, it was still the usual chilly January weather.

One thing that Mariah made a point of not addressing on Twitter is the release of her ex-husband Tommy Mottola's memoir, Hitmaker, which hit store shelves on Tuesday. In his book, Tommy details his troubled relationship with Mariah, which he calls both "a fairy tale" and "absolutely wrong and inappropriate." The couple divorced in 1998.
