The 24-year-old actress admitted she initially expected the star to be vain because of his achievements as an actor.

She said: "I love him. Because of all the success, you expect him to be a little bit of a jerk, or at least a little bit vain. And he's not vain."

Amanda, who rose to fame in teen comedy Mean Girls in 2004, admitted she chose to star in Dear John, about the letters sent between a young wife and her soldier husband fighting a war, because she wanted to take a more serious leading role.

She added: "I wanted to be the romantic lead in something. When you're playing somebody who's going through a lot -- frustration and hardship -- you're just purging all your emotions, and it feels really good to do that."

Amanda, who is dating British actor Dominic Cooper, recently revealed she found kissing people on movie sets "weird." She said: "I'm sure a lot of girls are probably really jealous of me. It's crazy. Being an actor is weird sometimes because you get used to making out with all these different people."
