Report: Ugly Behavior by Lindsay Lohan on Ugly Betty Set

Reportedly, everyone on the set of Ugly Betty has seen Lindsay Lohan nude.

But we'll get to that in a moment.

According to The New York Post, Lohan's behavior on the set of the ABC show has been so abysmal that the series has cut the number of episodes she'll appear on from six to four.

“It was a mess. Lindsay would show up every day with an entourage of people," a source said. "She smoked 24/7, and after she left, they had to repaint her dressing room it was such a mess... [Lindsay] would obsessively cut pictures of herself out of the tabloids like she was creating some sort of scrapbook and refused to go on set until [America Ferrera] was there - it was a power play.”

We buy the entourage, and the smoking; but they had to repaint Lohan's dressing room? For what possible reason?

The insider said that a scene in a future Ugly Betty episode involves Ferrera's character pulling down the pants of Lohan's character; but when the action took place, “Lindsay wasn’t wearing any underwear,” and the entire crew learned why she's referred to as "Firecrotch."

However, a friend of Lindsay's countered that accusation:

"Lindsay wears underwear all the time now. She was wearing a G-string. And it was America’s fault. They were rehearsing the scene and America wasn’t supposed to pull Lindsay’s pants down - but she did. Lindsay was so embarrassed, she started crying.”
