HER FLING WITH DEREK

The diva, 50, confirms that her songs “The Roof” and “My All” were about her fling with New York Yankees legend Derek Jeter, 46, after they met at a dinner party — and shared a hot kiss on the roof of his apartment building. “I can never forget that moment,” says Mariah, who hooked up with the star athlete while her marriage to Tommy Mottola was crumbling in 1996.
