Robert Pattinson has said he often feels like a con artist at auditions.

The former Twilight star admitted he has learnt to cope with those nerve-racking meetings when he is going for a role, by trying to take it in his stride.

"I'm quite good at doing meetings. I don't know, I just become a bulls**t artist! That's when I start acting! I'm really much better at doing it when the cameras aren't rolling..." he told The Guardian.

Robert admitted he goes through 45 minutes of "neuroses" before the auditions begin.

"I just can't... I literally can't do it," he continued. "It's just me looking uncomfortable, trying to put on an American accent... or sitting in the corner, making myself throw up and punching myself in the face."

The 28-year-old actor, who has since worked with David Cronenberg and stars in David Michod's dystopian thriller The Rover, also revealed that starring in the Twilight films as vampire Edward Cullen was probably his most challenging role to date.

"I think Twilight's probably the hardest part I've done, because to do it for five movies, it's really hard to think of stuff that's maybe not boring. Especially if you don't die," he said.

"Because what's the drama? You're not scared of anything! And that's the whole essence of drama: life and death."
