Lindsay Lohan claims to be in a real life "Mean Girls" movie.

Samantha Ronson broke up with Lindsay Lohan, her girlfriend of two years.

Last Friday, Ronson hired five security guards to keep Lohan out of Ronson's sister's birthday party at Hollywood's Chateau Marmont. Lohan and her family stayed a floor directly above Ronson.

The next day, Lohan arrived at the house that she and Ronson shared to find that the locks had been changed.

Lohan told US Weekly, through a series of phone calls and emails, "I'm just really hurt! The whole situation is sick!"

The actress recounts the night by saying, "It's humiliating! It's the worst day of my life."

The Daily News reports that Nicole Richie walked by Lohan and said "Uck" the night of the Chateau showdown and "Sopranos" star Drea De Matteo said, "Come at me, b----."

RadarOnline.com reports that the following Monday, Lohan chugged an entire bottle of vodka in front of her mother, to drain away the pain.
