The Georgia Rule star, who recently took a romantic Bahamian vacation with Best, was enraged when Calum checked into the hotel with another woman.
A source told Star magazine, "Lindsay checked in with another guy, probably to try and make Calum jealous. She tried calling him but she couldn’t get through."
The actress proceded to party until 1:30 in the morning, when she passed out in the hotel lobby.
Another source claims that Lohan was writhing on the floor, and it was apparent that the star was not wearing any panties. No one came to her aid, not even her bodyguard who witnessed the incident, until a hotel manager ordered her to her room.
In the room, Lohan continued to try to telephone Best, but without success. The actress then went banging on his door. When he opened the door and Lohan saw the other woman in the room, she began screaming.
Lindsay Lohan was asked to leave the hotel at 5:30 in the morning.
