Despite rumors of their break up making rounds, Robert Peterson has been reported as very much fond of kissing co-star Kristen Stewart.
They are part of the filming of The Twilight Saga that demands the pair to lock lips, though they are not bound to do so in a contract. Still, Roberts says that the kiss came naturally and he liked it.
He is reported to have said that in Eclipse, kissing was bit more natural and there were many kisses in that film. In New Moon and Twilight it was enjoyable to kiss but in Eclipse he had more understanding with co-star Bella and that made kissing easier.
