Shia LaBeouf has displayed moments of odd behaviour over the last few months, all involving twitter.

But the 27 year-old has really out done himself with his latest bizarre tweets.

LaBeouf was surrounded by controversy back in December (2013) after he was accused of plagiarising the work of graphic novelist Daniel Clowes in his short film 'Howard'.

In the first of two tweets, posted earlier today (Wed 22nd), the actor attempted to justify his plagiarism and branded his personal twitter account as "meta-modernist performance art."

The title of the lengthy tweet, 'Twitter As Art #stopcreating', uses the hashtag seen on many of his apologies posted on the social media site, and is all part of a project.

LeBeouf writes, in the tweet, the issue with American art is that "we are becoming a cut and paste culture."

"My Twitter @thecampaignbook is meta-modernist performance art. A performative redress which is all a public apology really is," he states. "All art is either plagiarism or revolution & to be revolutionary in art today, is to be reactionary."

Shia claims that his actions on "twitter started a broad cultural discussion that needs to be had about plagiarism in the digital age & celebrity/social media absurdity." Adding, "Intentionally oscillating between, hope and doubt, sincerity and irony, knowingness and naivety, construction and deconstruction. I addressed the world."

The 'Fury' actor concluded, "My actions here are only as interesting as the conversations that come about as a result of them. The fact that they were started at all is a positive thing. Thank you. I'm sorry - Shia."

Was that an apology?

Another post followed, it displayed a list of what qualifies as performance art and defines what performance artist is.

A couple of key aspects on the list read, "Performance a#RT reveals the vulnerability of living," with another saying, "Performance a#RTists should not have slef control over their life."

Each post was deleted shortly after.
