Los Angeles: Troubled actress Lindsay Lohan reportedly crashed into an after party for the premiere of Leonardo DiCaprio's new film, 'J Edgar'.

Though the 25-year-old insisted she had an invite to the bash, she argued with security at length and dropped multiple celebrity names in an effort to get inside. She is said to have caused such a scene that other celeb guests felt uncomfortable, reports said.

"Eventually they let her in, but she made everybody uncomfortable. She was aggressive and random, storming around. She tried to get to Leo, but he was surrounded by his security and a posse of his friends. Clint Eastwood and Leo and Dustin Lance Black were talking, and Lindsay sent one of her aides over, demanding to get a photo with them, but security shooed them away," a source said.

When asked Lohan's representative about the incident, he said, "I am not aware of her asking for photos with Leo or Clint. She was never asked to leave, she had an invite."

Lohan was recently sentenced to 30 days in jail for violating her probation, which will be reduced to one day because of overcrowding in jail.
