'Twilight' Director Talks About Kristen Stewart & Robert Pattinson's Romance

Catherine Hardwicke, the director of 'Twilight' has all but confirmed the long-rumored romance between costars Kristen Stewart and Robert Pattinson.

"I didn't have a camera in the hotel room, I cannot say," she told TIME magazine about when things starting heating up. "But in terms of what Kristen told me directly, it didn't happen on the first movie. Nothing crossed the line while on the first film. I think it took a long time for Kristen to realize, O.K., I've got to give this a go and really try to be with this person."

Hardwicke noticed the chemistry between Pattinson, 23, and Stewart, now 19, right away and discouraged him from carrying it from the screen to the set.

"After I cast him, I told Rob, Don't even think about having a romance with her," she said. "She's under 18. You will be arrested."

The young lovebirds are now in Madrid promoting 'Twilight: New Moon,' which opens November 20.
