Kristen Stewart misses being on the 'Twilight' set with Taylor Lautner because the pair have such a strong Bond.

The 21-year-old actress got close to her co-star while filming the vampire movies and although they no longer see each other as frequently as they used to, Kristen makes sure they keep in touch as much as possible by phone and email.

She said: "When I don't see Taylor for a while I take out my phone and call him. It's not like I see him all the time or every day, it's just that when you work with people like that, you can give so much. It's so comfortable, you can do no wrong - they've got you. We get along together and I think it shows."

Kristen - who is dating her on screen 'Twilight' lover Robert Pattinson - insists she is close to all her castmates and she doesn't think she could have made the five movies in the series if they didn't all get on so well.

She explained: "I couldn't have done this without them. I can't imagine what this movie would have been if I didn't have really solid - and always growing - relationships with them."

The 'Twilight Saga: Breaking Dawn - Part 1' is out in cinemas this weekend.
