Robert Pattinson has revealed "no one can understand" what he has gone through with Kristen Stewart.

The 24-year-old actor - who is rumoured to be dating his 'The Twilight Saga: Eclipse' co-star - admits the brunette beauty is "wonderful" and says they have been on a magical "adventure" together.

He said: "Kristen and I have lived a great adventure together with the 'Twilight' films. We are very close and no one can understand what we've gone through together the last few years.

"When we're together, we understand each other so well that we don't have to say a lot to explain what we're thinking. Kristen is a wonderful girl."

However, the big screen heartthrob - who stars as vampire Edward Cullen in the movie franchise - admitted he shares his Alter Ego's lack of success with the opposite sex.

He explained to new! magazine: "I do bear some similarities in the sense that I'm not good at romance. I also think I lack basic finesse when it comes to women.

"I give up too easily even if I'm very attracted to someone."

Despite having to cope with the attention of his legions of female fans, Robert is still shy when it comes to dealing with his admirers.

He admitted: "I don't want to disappoint girls who might think I'm very cool and smooth, which I'm not, I'm afraid. I'm still quite shy, although that seems to be something of an attraction for women."
