WE KNEW IT!!!
Mariah Carey is finally admitting what fans have suspected for decades ... two songs from her classic '97 album "Butterfly" are about her fling with Derek Jeter!!!
Yep, Carey says both "The Roof" and "My All" were all about the NY Yankees legend ... who she began seeing back in 1997 after meeting him at a dinner party.
Carey was married to music mogul Tommy Mottola at the time, but the marriage was on the rocks ... and Carey was clearly infatuated with Jeter.
