A source from the Anger Management set says that, by the time Lindsay Lohan was done shooting her guest spot on Charlie Sheen's FX comedy, the cast (Sheen included) and crew were thinking that hiring her wasn't worth the aggravation. "She was a colossal pain in the ass," one source says. “The first day was fine," notes the insider. "She showed up early and did her job. But on the second day, from the moment she arrived she did nothing but hold up the production. She would sit in her trailer and stall and she delayed until she up and left for her boyfriend's concert...She held everyone hostage."
