Celebrity starlets Lindsay Lohan and Paris Hilton are embroiled in a vicious, foul-mouthed internet fight.
The pair - who were once friends - have been trading insults on popular social networking site Facebook.
Mean Girls star Lindsay branded the hotel heiress a "b***h" and called her "pathetic" before launching a four-letter tirade after Paris had set up a group on the site called 'Firecrotch', referring to the actress' red hair.
But Paris hit back, saying it was her who was the pathetic one because she has set up a Facebook group about her first called 'Paris Wets Herself', which refers to a couple of alleged incidents involving the 27-year-old blonde.
The former friends initially fell out over Greek shipping heir Stavros Niarchos III, who they have both dated.
Lindsay, 23, is openly gay and dating DJ Samantha Ronson, 31, while Paris is in a relationship with Good Charlotte guitarist Benji Madden.
