Falling Apart| Lindsay Lohan
But the mood changed later that night when Lohan arrived at a pal's gathering. There, at least one person protested Lohan's partying – her assistant Tarin Graham. The two allegedly argued, and Graham declared she was quitting. Graham then apparently called her mother to pick her up, and Lohan gave chase.

What happened next may finally help Lohan turn a corner. "Forever people were talking about her wild and crazy ways, but she was still booking projects and making movies," says a friend. With her life in ruins, "she's getting scared." Others worry it may be too late. Lohan's party buddies "are not friends," says a close source. "They are enemies. She's got to realize that and walk away. If she doesn't, she could be the next Anna Nicole Smith. That's what I'm afraid of."
