Star of the "Transformers" movie, Shia LaBeouf was met by a crowd of reporters upon his release on Friday after being arrested for allegedly disrupting a Broadway musical in New York. LaBeouf was charged with two counts of disorderly conduct, one count of trespass, one count of criminal trespass and harassment in the second degree. (Reuters)

Adulthood just doesn’t agree with Shia LaBeouf, does it? At 27, LaBeouf announced earlier this year in a tweet that he was “retiring from all public life.”

Perhaps he’s already grown bored — because Thursday night, LeBeouf, who turned 28 earlier this month, was arrested essentially for behaving like a toddler. The former “Transformers” actor apparently couldn’t sit still in his seat at a Broadway performance of “Cabaret.” He was forcibly removed — during the first act, no less — for allegedly smoking inside the theater and generally causing a disturbance.

LaBeouf  “was annoying other theater goers by slapping random people on the behind and on the back of the head,” according to Page Six, which also said LaBeouf was put in a mask when he wouldn’t stop spitting.

In a few weeks, LeBeouf may go on a talk show and reveal this was just another chapter in his “performance art” — only this time he was just doing a public performance of “Little Bunny FooFoo” with cigarettes. Or we’re going to hear the words, “It’s for a role.” (Maybe there’s a Mel Gibson biopic coming out that no one knows about yet.) LaBeouf, who recused himself — or was booted, depending on who you ask — from another turn as Sam Witwicky in “Transformers 4,” claimed he was doing performance art when he walked around the Berlin Film Festival with a paper bag on his head that said “I AM NOT FAMOUS ANYMORE.”

That culminated with an installation at a Los Angeles gallery called #IAMSORRY, which appeared to be a deliberate rip-off of Marina Abramović’s “The Artist is Present.” LaBeouf sat in the gallery with the same paper bag over his head and made eye contact, but refused to speak.

In December, following accusations that he’d plagiarized the work of graphic novelist Daniel Clowes for his short film “Howard,” which he made for the Cannes Film Festival, LeBeouf hired a skywriter to write “I am sorry Daniel Clowes.” He also apologized in a series of tweets — that were plagiarized from other celebrity apologies.

Someone caught LeBeouf leaving in handcuffs and posted it on Instagram with the caption “Not a clear pic but Shia Labeouf is getting arrested by the back door of The David Letterman Show.” The Ed Sullivan Theater, where Letterman’s show is taped, is just a few hundred feet from Studio 54, where “Cabaret” is being staged.

Composer Benj Pasek also confirmed the arrest via Twitter:
