Rachel Uchitel was left "sick to the stomach" after a New York magazine editor sent her a tormenting text message about her late fiancé who died in the September 11 terror attacks, RadarOnline.com has exclusively learned.

Uchitel, the first mistress linked to Tiger Woods, said Steppin' Out's Chaunce Hayden fired off an inflammatory message after a botched photo shoot that read: "Your husband (sic) didn't die on 9/11.... he escaped. I feel his pain."

Uchitel's 32-year-old love Andrew O'Grady, not husband as Hayden had taunted in his text, was killed in the 2001 Twin Towers attack.
