Shia LaBeouf has exclaimed that recent accusations of plagiarism have all been in the name of "performance art".
The ex-Transformers actor has been criticised in the press after it was revealed that his short film Howard Cantour had plagiarised Daniel Clowes graphic novel.
LaBeouf - who claimed earlier this month that he was "retiring from public life" after his war of words with Clowes - is now said to have tried to justify his actions on Twitter.
According to Gossip Cop, Shia wrote on Saturday (January 18): "Performance art has been a way of appealing directly to a large public, as well as shocking audiences into reassessing their own notions of art and its relation to culture.
"All art is either plagarisum (sic) or revolution & to be revolutionary in art today, is to be reactionary.
"In the midst of being embroiled in acts of intended plagiarism, the world caught me & I reacted."
He went on to explain his Twitter user name, The show began. I became completely absorbed, oblivious to things around me."
The actor also explained that his Twitter handle, @TheCampaignBook, represents "meta-modernist performance art," adding that his actions have sparked a "broad cultural discussion that needs to be had about plagiarism in the digital age & celebrity/social media absurdity."
Shia also poked fun at his recent scuffle in a London pub, ending his rant with the hashtag: "#StopHeadButting."
