Artists Nastja Säde Rönkkö and Luke Turner confirm that an "incident" did in fact take place, with Ronkko tweeting that they "put a stop to it."
Turner also responded to journalist Piers Morgan, who has made no secret about doubting LaBeouf's claims.
Turner says the woman "ran out" when Morgan asked why they let the 28-year-old's alleged rapist "just walk away."
In a new interview with Dazed and Confused magazine, LaBeouf described the alleged disturbing incident in an email to writer Aimee Cliff. The controversial 28-year-old actor's February art installation performance consisted of him meeting members of the public one by one alone in a room at a gallery in Beverly Hills, California, sporting a tuxedo and a bag over his head.
"One woman who came with her boyfriend, who was outside the door when this happened, whipped my legs for ten minutes and then stripped my clothing and proceeded to rape me," he wrote. “There were hundreds of people in line when she walked out with disheveled hair and smudged lipstick. It was no good, not just for me but her man as well."
LaBeouf called the incident traumatic and "painful."
"On top of that my girl was in line to see me, because it was Valentine's Day and I was living in the gallery for the duration of the event--we were separated for five days, no communication," he wrote. "So it really hurt her as well, as I guess the news of it travelled through the line. When she came in she asked for an explanation, and I couldn't speak, so we both sat with this unexplained trauma silently. It was painful."
This has been quite the year for LaBeouf, who in addition to his controversial art installation piece, also pulled out a tooth and cut his own face
for his role in Fury
, and got arrested during a June performance of Cabaret
in New York City.
