Robert Pattinson and Kristen Stewart only had eyes for each other as they arrived at San Diego fan convention Comic-Con yesterday, to talk Twilight Breaking Dawn Part 2, and, of course, Fifty Shades of Grey.
Dressed in a neon BCBGMAXAZRIA skirt, a cropped white tee and black hi-top boots, Kristen Stewart was unusually smiley as she sat by Robert Pattinson on the panel, answering questions on the new movie - and its steamy sex scenes.
Speaking of their struggle to maintain a suitable rating during the saucy scenes, filmed with off-screen boyfriend Robert Pattinson, Kristengiggled: 'The ratings, man! [It's] a tricky thing.
'In the second one, we just wanted to be animals. We're not human anymore. How do you do that? We tried, and they told us it was rated R, and we were like [snaps fingers]. So, yeah, I'm going to stop.'
During the day Robert Pattinson also opened up on racy novel Fifty Shades of Grey, joking to MTV's Josh Horowitz: 'I would just sit there and lick the pages.'
Last week, the rumour mill went into overdrive, amid reports Robert Pattinson and Kristen Stewart were set to take on the hotly-tipped roles of Anastasia Steele and Christian Grey in the film adaptation of racy novel, Fifty Shades of Grey.
But fans' excitement was soon extinguished by author E. L. James, who confirmed she's not keen on having either Rob or Kristen take on the Fifty Shades' roles.
