Robert Pattinson 'Kristen a cooking nerd'

Robert Pattinson says his girlfriend Kristen Stewart is a cooking “nerd”.

The actor has revealed the actress is obsessed with culinary TV programs and would watch them in-between takes on the set of the last two Twilight Sagamovies.

“She’s a nerd when it comes to cooking, especially on set. It was bizarre! She’d be in the trailer and the cooking channel was always on,” he said.

Robert who plays vampire Edward Cullen in the film franchise admits he is very protective about his girlfriend and he won’t tolerate people unfairly criticizing Kristen, who portrays Edward’s lover Bella Swan in the movie series.

“I’m protective of anyone close to me. If people say anything about my family or friends, I feel protective and that’s the one time I feel like I really have to do something about it,” he said.

Robert and Kristen have been in a relationship since 2008, but only publicly admitted their romance last year.
