Robert Pattinson only reads bad reviews of his work.

The 29-year-old actor - who shot to fame as vampire Edward Cullen in the 'Twilight Saga' - admitted he actively seeks out reviews which slam his acting.

He said: ''I do read reviews to a fault and it's an awful thing to do. It's an addiction. And you only read the bad ones too, just to foster hatred, self-hatred, self-loathing. It's a weird habit.

''I definitely feel like I need to prove something and I'm not sure exactly what that is. So that's probably what my turmoil is.''

Director Anton Corbijn - who worked with Robert on 'Life' - says the young star doesn't see how talented he actually is.

He told The Observer Magazine: ''I don't know if it's insecurity but he's far more gifted than he gives himself credit for. Obviously success came relatively easy for Rob with 'Twilight' and ever since then he's take on left-of-centre roles to prove - I guess to himself - that he is an actor and not just a famous act. That's really courageous of him but he underestimates his own quality. He's nervous. I think he beats himself up a lot - unnecessarily so in my eyes.''
