Actress Lindsay Lohan, who has been sentenced 30 days in jail, reportedly gatecrashed into the premiere party of Leonardo DiCaprio's new movie "J. Edgar" The troubled actress crashed her way into an after-party for the premiere and made other guests "uncomfortable."

Lohan argued with security and dropped multiple celebrities' names in an effort to get inside. "Eventually they let her in, but she made everybody uncomfortable, " nypost.com quoted a source as saying.

"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, " the source added.

However, Lohan's representative has denied that she crashed the event and said she was invited by a fellow guest. "I am not aware of her asking for photos with Leo or Clint, " the rep said. "She was never asked to leave."
