Robert Pattinson has joked that he would like to lick the pages of the erotic novel ‘50 Shades of Grey’. The ‘Twilight’ actor made the comment while promoting his ‘Breaking Dawn: Part 2’ at Comic-Con on Thursday. When questioned, he and girlfriend Kristen Stewart were mum on whether or not they’ve been reading E.L. James’s sex-filled bestseller – but the 26-year-old actor knew what he would do if the risque read was right in front of him. “I would just sit there and lick the pages,” People magazine quoted him as telling MTV. “What are we live on?” he said, realizing that his silly response would gain attention. His 22-year-old girlfriend on the other hand, was less upbeat about the topic. When asked if she reads the novel in a book club with Pattinson and fellow ‘Twilight’ star Taylor Lautner, she said, “That would be disgusting.”
