Comic Con is underway, which means a major Twilight takeover of San Diego.

Of course, with the saga coming to an end -- the last film Breaking Dawn, comes out November 18 -- fans at the convention are hanging on every word stars (and real-life lovers) Robert Pattinson and Kristen Stewart speak.

STewartPattinsonMealTwilightBreakingDawn230.jpgComic-conners were especially on the edge of their seats when the two started talking about the potentially controversial sex and birth scenes in Breaking Dawn -- their characters, Bella and Edward, marry and consummate their union (in a word: hot.) Then, Bella gives birth to a vampire/human hybrid baby.

"The wedding was [filmed] Secret Service style insane," said Stewart. "There was no cell phone or email." Filmmakers have taken great care to keep Bella's dress under wraps.

While Stewart says the wedding is "beautiful," Pattinson called the birth scene "hardcore." He told

    "For a fantasy ... that has kind of a youngish audience, it goes very far. There was no other way to do it."

Pattinson also talked about filming the honeymoon scenes ... get the details after the jump!
