Lindsay Lohan is facing further press with the publication of photos showing her holding a knife to a pal's throat. Last month Lohan was reportedly left "inconsolable" when a tape leaked to British newspaper The News of The World appearing to show the actress snorting cocaine with friends in a Los Angeles club bathroom.

Now the same newspaper has printed disturbing photos of the star - currently in rehab - at a house party four months ago. In some shots she slides a knife towards a friend's neck, before holding the point towards her own mouth in others.

Last week some of the actress' close pals approached Star magazine with tales of her increasingly bizarre behavior, and fears she may be harboring suicidal thoughts.
