Kristen Stewart Missed Pattinson On Set

Kristin Stewart missed 'Twilight' co-star Robert Pattinson when he wasn't filming with her.

The 19-year-old actress - who plays Bella Swann in the vampire saga - said she found it hard to deal with the disappearance of Robert's character Edward Cullen for a large chunk of the filming.

She said: "For Bella in this film, Edward leaving her is like physical withdrawal. She is an addict when it comes to this boy.

"I have a breakup scene with Rob in the movie, but that's not what intimidated me. It was the absence of him that was scary."

The American actress also denied that she was dating 23-year-old Robert in real life.

She added: "The whole rumour tabloid stuff is so obviously false to me, and I knew it was false even before I became a part of it."

She said rumours about the two of them becoming romantically attached had been like "a soap opera" but she doesn't take any of it personally.

She said: "It might seem real to fans, but it isn't."

The 'Twilight Saga: New Moon' is released in cinemas on November 20.
