Rachel Uchitel -- Tweeting from Ground Zero

Rachel Uchitel visited the memorial at Ground Zero this morning to pay her respects to those who lost their lives on September 11 -- including her fiancé at the time, James Andrew O'Grady.

Uchitel is currently embroiled in a spat with Page Six Magazine, which ran an article that quoted her as saying, "I believe Andy was meant to die because he was too good."
