Actor Robert Pattinson insists he always stays grounded because he isn't very confident.
The "Twilight Saga: Breaking Dawn - Part 2" actor says it's very easy for him to stay grounded despite all his success because he doesn't have enough confidence to get arrogant.
"I'm quite an insecure person, so it's not hard for me to stay grounded. You have to be pretty dumb to let your head get big, especially when everything about your life is reported. Everyone knows you're just a vain moron," femalefirst.co.uk quoted the 26-year-old as saying.
