Lindsay Lohan's much-hyped guest spot on the TV show Ugly Betty isn't turning out too well. Signed up for six episodes, the singer will now only appear in four. The reason? The usual list of diva-like behaviour.

One production source said, "It was a mess. 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."

In addition, Lohan "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 was there - it was a power play."
