Lindsay Lohan & Vanessa Minnillo Knife Photos Hit Web

The photos (posted by celeb photo agency x17) were apparently taken in June 2006 and show Lohan, 20, holding a knife to Minnillo's neck, then pointing the blade into her own mouth.
Minnillo, 26 – Nick Lachey's girlfriend – is seen pulling down Lohan's tank top and pointing a knife toward her bared chest.
In another shot, Lohan makes an obscene gesture, flashing the offending digit and displaying chipped nail polish.
It's not known what prompted the pair's photo session. The pair's rep didn't respond for comment.
Meanwhile, the New York Post on Tuesday speculated that the photos could hurt Minnillo's TV broadcast career. (She recently parted ways with MTV's TRL, and she has worked as a correspondent for Entertainment Tonight.) But her rep denied to the Post that Minnillo has lost any work because of alleged bad behavior.
