UPDATED: The actor wore a black tux and bow tie, plus a bag with the words "I am not famous anymore" written on it.

BERLIN -- Shia LaBeouf topped off his headline-making day with a peculiar fashion statement on the red carpet at the Berlin Film Festival gala premiere for Lars von Trier's Nymphomaniac, Volume I Sunday night.

The actor accessorized his black tuxedo with a black bow tie and a paper bag with the words "I am not famous anymore" written in black paint on it. LaBeouf, 27, has been using the catchphrase repeatedly on his Twitter account for several weeks.

The troubled actor's bizarre behavior started Saturday night when three young men tried to snap a picture of him at the lounge at the Ritz-Carlton, only to have LaBeouf lunge toward them. Several acquaintances of LaBeouf quickly intervened and defused the situation.

Also in Berlin to promote the film are von Trier and his stars Christian Slater, Stacy Martin, StellanSkarsgardandUma Thurman.
