'Ruffian' Shia LaBeouf

Shia LaBeouf has a "dark side".

The 'Wall Street: Money Never Sleeps' actor - who is dating actress Carey Mulligan - could never be as squeaky-clean as other Hollywood stars because he has always been "a ruffian".

He explained: "I've never been like Zac Efron. I am a bit of an a*shole. I have a dark side. I'm a bit of a ruffian. I've never tried to be anything else. I was never educated properly because I got kicked out of every school."

Shia has also admitted the only reason he wanted to be a Hollywood star was because the large pay would help ease his family's financial problems.

He added: "Initially, it was all money driven. I didn't give a s**t about arts. We were as broke as balls, so I just wanted to move my family into better digs."

The 23-year-old star also revealed he has banned himself from celebrity parties for the sake of his career as he doesn't trust himself around alcohol.

He told Britain's Glamour magazine: "I am not good at going to parties and doing the schmoozy thing. I drink to get drunk, so I don't go to social things for a couple of drinks because two and two makes 12. The way I deal with being at those functions is to get wasted. And that jeopardises what I love and what keeps my family fed, and builds my self-worth. I'd risk too much."
