June 14, 2006 -- PARIS Hilton is so upset that Lindsay Lohan has been seeing her ex, Greek playboy Stavros Niarchos, she screamed insults at Lohan at Butter on Monday night. Witnesses report Hilton went up to Lohan and shouted, "I can't believe you and Stavros! You are ridiculous!" After taking more insults and curses, Lohan said, "That's how you say hello? I don't need to respond to you." Lohan promptly left. A rep for Lohan said, "Correct. Paris tried to pick a fight with her and started screaming at her, but Lindsay took the high road." After Lohan left, Hilton did a striptease for N.Y. Knick David Lee, Eli Manning and a bunch of other N.Y. Giants.
