Why can't this girl get it together?

Lindsay Lohan let loose at the GQ Men of the Year dinner the other night, hurling insults and reportedly making a fool of herself. When the Bobby actress arrived at the party with her mom, she "flipped out" to see Jessica Biel there with her assistant, who previously worked for Lohan. "If she stays, I'm outta here!" Lohan allegedly screamed. "I can't look at that girl! I can't believe you would allow an assistant in here - she doesn't belong in here!" A witness told PageSix, "It was really uncalled for. Jessica and everyone else ignored her." Other celebs at the party avoided Lohan after her bratty behavior and after overhearing her rant against Biel, Will Ferrell reportedly said, "Who cares about that freak anymore, anyway?" to Leonardo Dicaprio, Al Gore and Ben Affleck. Lohan proceeded to make out with Johnny Knoxville, but stopped when her ex Harry Morton appeared. "Harry had been called by Lindsay, and he arrived with a bunch of her friends, and then they all left together, including Johnny. It was weird," said a source. "[Lohan's mom] did a lousy job of reining in her daughter, and it looked like she just used Lindsay to get into the party in the first place."
