Robert Pattinson Is Envious Of Another Man: Robert Pattinson is in the news again and this time it is for his in-secured feelings with girl friend's co star Viggo Mortensen. Sources say that Robert Pattinson is in a 'panic situation'.

The movie , 'On the Road' that is directed by Walter Salles, has said to have a great number of sex scenes and a threesome intimate scene , which Kristen Stewart and the handsome Viggo Mortensen share.

Robert Pattinson is feeling so insecure that he has decided to stay on the sets of this film. He has not been given any part to play in the drama . But, when his girlfriend is engaged in the intimate scene with Viggo Mortensen, Pattinson will mark his presence.

Robert Pattinson wants to make sure that these scenes will be a pretense right from the start of the film to the very end of the production.

In spite of Kristen Stewart telling Robert that she doesn't want him on the sets as it would be uncomfortable , he insisted that he is going to be there.

The 24 year old, Robert Pattinson is free until his next filming of his Twilight series begins , so in this case he has all the time at the tip of his fingers to keep a watchful eye on girlfriend Kristen.

Is his jealousy justified though? We all know that this British actor is a hunk and is very much desired by all women over the world, so he shouldn't pay attention to Viggo Mortensen as he is just another man and not the 2nd Robert Pattinson.
