Lindsay Lohan caused chaos at the Los Angeles premiere of Scary Movie 5 by arriving at the event 30 minutes after the red carpet closed.
The Mean Girls star, who makes a brief appearance in the spoof film opposite Charlie Sheen, left guests and reporters waiting at the movie's official L.A. screening on Thursday night (11Apr13).
Lohan turned up 30 minutes after the red carpet was officially closed, just as the movie screening was due to be getting started at the city's ArcLight Cinerama Dome. She was able to quickly pose for some pictures with Sheen before hurrying inside the cinema.
The actress hinted at the drama in a post on her Twitter.com page on Thursday, revealing she had been to see a dentist in the hours before the premiere. In a message directed at her dentist, she writes, "Sorry for the delay... but thank you for your amazing help today best dentist ever."
Talking to reporters at the premiere prior to Lohan's arrival, the film's director David Zucker revealed the troubled star had been late numerous times when she was due on set, but insisted she is still a good actress.
He says, "She's a troubled human and she was late a lot to the set (but) she knew her lines and she's a good actress... This seems to be the business for all these addictions and craziness. Anybody has the potential to come back and straighten out."
Actress Ashley Tisdale, who also appears in the film, adds of Lohan, "I just know that she's a really talented actress, so I think if anything I just would love to see her do more movies. I've known her for a really long time."
Lohan is due to begin a 90-day stint in rehab by 2 May (13) as part of her punishment for lying to police over a car crash in California last summer (12).
