lindsay lohanLindsay Lohan’s guest role in Ugly Betty has reportedly been reduced from the agreed-upon six episodes to four because Lindsay was a pain on set.

An on-set source told the New York Post that “it was a mess” when Lindsay filmed her segments last month: “Lindsay would show up every day with an entourage of people. She smoked 24/7, and after she left, they had to repaint her dressing room it was such a mess.

“[She] 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 [the show’s star] America Ferrera was there - it was a power play.”

However a source close to Lindsay played down the issues, telling the newspaper: “An entourage? Yeah, she had her sober companion with her, as well as her manager, assistant and [girlfriend] Samantha Ronson. Her publicist was there a couple of times. But so what?”

The source added that America was to blame for Lindsay’s cameo being cut short and not the Freaky Friday star herself: “America was mean to Lindsay. Producers give her too much power.

“Lindsay didn’t do the last two episodes because America didn’t like her and got her kicked off.”

Lindsay’s spokesperson confirmed the episode reduction but insists “she had a lovely time” on the set.
