Alright!''The 30-year-old star says she is terrified if she watches herself on-screen she will discover she's a bad actress.She said: "And sometimes I'm scared that I'm going to be hit with this awful realisation that I've been s**t all these years."I'd rather be oblivious and that way I could still try to get better, as opposed to being depressed about how crap I was.'
