Jackson Rathbone talks Breaking Dawn. Kristen's Wedding Dress and Wrap Party

E!OnLine"[We have] another five years before we can show crowning in a PG-13 film," said an almost giddy Jackson, who plays broody brother Jasper. "I was pushing for the X-rated version, personally—vampire sex and crowning, the whole nine yards."

"We had 20 people covering Kristen Stewart so that they couldn't get pictures of her wedding gown. It was an insane lockdown that day. It felt more like a prison," says Jackson.

"I don't think anyone remembers it, that's how crazy it was," Jackson says of the wrap party. "Everyone was like, ‘There was a wrap party?' "
