Kristen Stewart has spoken about the tight security measures that surrounded the wedding of Edward Cullen and Bella Swan in The Twilight Saga: Breaking Dawn - Part 1.
Stewart - who plays Bella - described how the studio was locked down, with all mobile devices confiscated.
She told fans at San Diego's Comic-Con: "It was insane... The crew was completely inconvenienced; there was no cell phone or email.
"I said thank you so much, because if this (wedding) dress gets on the internet, I'll die!"
Stewart also spoke of being incredibly nervous for the scene, saying: "When I got to set I was as nervous and terrified as I expected myself to be... I had to be locked into the dress to protect it."
The Twilight Saga: Breaking Dawn - Part 1 is released on November 18.
