While Lindsay Lohan reportedly started off being "so professional" while shooting her guest-starring role on "Glee" last week, sources say that she has devolved into being a "total nightmare."
"Lindsay was a total nightmare yesterday," a source told E! News, characterizing Lohan's showing on the set on Wednesday. "She was three hours late in the morning, and when she did finally arrive, she just didn't want to be there. She did not want to work. She had not memorized her lines, and she kept disappearing so no one could find her."
