In the latest in a string of bizarre behavior, Shia LaBeouf donned a paper bag on his head to walk the red carpet at the premiere of Lars Von Trier’s “Nymphomaniac: Part 1” at the Berlin Film Festival Sunday night.

While the rest of his wardrobe — a black tuxedo and bow tie — suited the event, the message written in black paint over the paper bag is in line with his ongoing Twitter stunt. It read “I AM NOT FAMOUS ANYMORE,” which the 27-year-old star of “Transformers” and “Indiana Jones and the Kingdom of the Crystal Skull” has been repeatedly posting on his Twitter account since Jan. 13.

Just earlier that day, LaBeouf had stormed out of a press conference after responding to a single question about performing sex scenes in the explicit film.

“When seagulls follow the trawler it is because they think sardines will be thrown into the sea,” he said before abruptly leaving the stage.

The star was also caught on video head-butting a man in a London bar fight last month.

The odd behavior comes after LaBeouf had recently claimed to be “retiring from all public life” after being accused of plagiarizing Daniel Clowes for his short film “Howardcantor.com.”

“Nymphomaniac: Part 1” is to have a limited release in the US starting March 21. Along with LaBeouf, it also stars Christian Slater, Stacy Martin, Uma Thurman and Stellan Skarsgard.
