Robert Pattinson and Kristen Stewart's love scenes were filmed on a closed set.

The Twilight Saga: Eclipse's director, David Slade has revealed that Robert Pattinson and Kristen Stewart's love scenes were filmed on a closed set.

When asked if everyone crowded around to see the rumoured lovebirds in action, David said: “They [love scenes] can be uncomfortable to shoot so we had to get everyone really comfortable, there isn't any joking around, everyone is usually very profesional and we do a closed set.

And were the pair nervous at shooting such an important scene?

“They didn't seem to be. They seem very calm with each other. We shot that on the very last night and it just seemed to go wonderfully.”

He added: “I have to give complete credit to the actors for that as they just pulled it off.”
