London: Actor Robert Pattinson thinks his girlfriend and "Twilight" co-star Kristen Stewart is a "sexy goddess".

The 25-year-old admitted that Stewart, 21, looked "amazing" when her alter-ego Bella Swann turned into a blood-sucking "vampire queen" in their latest film "Breaking Dawn".

"She's a sexy goddess. She looked amazing. It was funny because Bella is that girl that is always tripping on things, and then, she turns into this elegant woman, like a vampire queen. Kristen had the best twist in the plot," a website quoted Pattinson as saying.
