The British actor – who is dating his ‘Twilight’ co-star Kristen Stewart – is happiest when he is in a relationship but prefers not to talk about it in order to maintain the “mystique”.

Asked if he is romantic, Robert said: “I guess I am when I like someone, I like being in love with people and yes, I guess I am quite sensitive to things.

“It’s important to preserve any mystique you have and also I just don’t feel it’s anyone else’s business.”

Robert admits his hardcore fans can be quite overwhelming but he received a great tip on how to deal with fame from his 'Remember Me' co-star Pierce Brosnan – who played James Bond in four movies.

In an interview with the Daily Mirror newspaper, he said: “We were in a restaurant and there were people looking over at us. They didn’t know who I was but knew who Pierce was and he went up to them and introduced himself.

“Anyone who looked round, he’d go up, shake their hand and ask how their evening was going. And I’d think, ‘What are you doing?’ But it works fantastically because no one treats you like you’re a side show attraction any more.

“They don’t look around after that and they go home and say, ‘Well, he’s a really nice guy.’ ”
