Actress Kristen Stewart found it "surreal" shooting the intimate scenes in "Twilight Saga: Breaking Dawn".

The 21-year-old's character Bella Swan gets intimate with vampire Edward Cullen, played by her real-life boyfriend Robert Pattinson, in the last two instalments.

"There are two big sex scenes in the two final films and we did them fairly early. It was so weird, it didn't even feel like we were doing a scene within a 'Twilight' film," quoted Stewart as saying.

"I was like, 'Bella! What are you doing? Wow! What is happening here?' It was very surreal," she added.
