Shia LaBeouf was escorted out of the LA opening of The Box nightclub by security Friday night after a confrontation with a pal of shock rocker Marilyn Manson. The “Transformers” star “exchanged terse words with a friend of Manson’s, who lunged over the table at Shia, and Shia lunged back. Security stepped in quickly and broke it up before any punches were thrown,” a source at the party hosted by Belvedere Red told us, adding, “Two security guards led Shia out holding his hands behind his head. His girlfriend, Karolyn Pho, was clearly upset and ran down the stairs after them. Outside, he fell onto a barricade. Swearing, he picked himself up and ran off.” Despite numerous witnesses at the party, also attended by Jon Hamm, Lindsay Lohan and Chelsea Handle
r, Shia’s rep said: “[He] actually left the club early as planned … he went to see one of the bands performing in the showcase and left after they finished … exiting through a crowded room was apparently misinterpreted. No altercation occurred.”
