Lindsay was full diva hogging the private bathroom all for herself and without any remorse.

"I saw Lindsay walk in and thought she'd come right out but she didn't, she was in there for like twenty minutes!" says a source. "People started getting mad. Twenty minutes is just unacceptable. You should just go in and out because you know people are waiting. But not Lindsay."

"These girls got so mad they started kicking the door and yelling nasty names at her like 'Bitch' and 'Slut,' but Lindsay still did not come out. So selfish!" Finally, after the eternal twenty minute wait, Lindsay came out — without an apology.

"Instead, she pointed her finger at everyone and looked everyone in the eye and asked, 'Which one of you said 'F**k You?' That is just not OK!'"

When the restless crowd started laughing at her, Lindsay's turned red. A girl yelled, "Firecrotch!" and Lindsay got visibly upset.

But keeping her cool, Lindsay gave a disgusted look to the crowd and said, "F**k you bitches," and fled the stairs.
