Shia Labeouf may have a squeaky clean image as Sam Witwicky in the Transformers films, but in real life he’s developing into something of a wild child. He’s so wild in fact that he’s developed a reputation for taking his own alcohol to showbiz events and getting royally bladdered (drunk, for our US readers).

This wouldn’t be a problem at most showbiz events, except that Shia had to accompany his girlfriend, English actress Carey Mulligan, to the Oscars this last weekend as she was nominated for her role in ‘An Education’. As Carey was also taking her brother and her parents, she’d warned Shia to be on his best behaviour.

(I’m taking) my mom, my dad and my brother.

According to the Daily Mail, Shia had caused an argument at the New York premier of An Education, after he’d sneaked in a bottle of whiskey and proceeded to crawl into it.

A source for the newspaper stated:

It was very awkward for Carey. Shia stayed in the bar drinking whisky all night and not chatting to anyone. It was very unchivalrous and they had a huge row.

Carey has said that he has to be on his best behaviour and support her at the Oscars – or not to come at all.

Carey didn’t win an Oscar on Sunday night, and Shia Labeouf didn’t turn up at all. Perhaps the ultimatum proved too much for him?
