Paris Hilton just can’t get along with anyone! Her ongoing feud with former best friend and Simple Life co-star, Nicole Richie, is matched today by her ongoing feud with actress/singer Lindsay Lohan.

Hilton and Lohan clashed yet again at a Malibu party this Saturday, where Hilton allegedly laughed and made “nasty comments” about Lohan to her sister Nicky Hilton and other guests. This marks the most recent conflict in a long running rivalry between the two actresses.

Many attribute the bad blood between them to rumors of Lohan, 20, dating Hilton’s ex, Stavros Niarchos. However Hilton has recently insisted that those rumors were false and that Greek shipping heir, Niarchos would never date Lohan. “He thinks she’s pathetic”, claimed Hilton to Britain’s Style magazine.

Hilton, 25, says she is happy to be single and has no intention of looking for another boyfriend, although she also admits she can’t wait to have children… when the time is right. In the meantime, she plans to focus on her music and acting career.
