Ah, Rachel Uchitel. Hers is a name that, unless you've been living under a rock or have somehow avoided splashy Tiger Woods mistress headlines, should ring a familiar, if slightly alarming, bell. The reason? Uchitel is now commonly known as Woods' Mistress No. 1 and ever since the scandal broke last November, she has been romantically linked to a increasingly dizzying list of high-profile individuals -- several of whom are, or were at the time, married. This week, her name and David Boreanaz's are almost synonymous, as he admitted to infidelities, and yep ... she's linked. So who exactly is this mysteriously powerful (and evidently irresistible) woman?
