Robert Pattinson has shared at least one overnight rendezvous with Gossip Girl’s Leighton Meester. Rob was recently spotted entering Leighton’s New York apartment — and he didn’t leave until 11 the next morning, an insider tells In Touch. “He ducked out of the building and hopped into a waiting car. He apparently spent the night with Leighton, and didn’t want anyone to know!” the insider says of the star, who even carried an overnight bag during his hasty exit. A friend of Leighton’s confirms the affair, adding that the pair are still in constant contact. “She’s having a texting romance with him, and is so into it. She talks with Rob almost daily,” her friend says. Leighton and her former boyfriend (and sometimes co-star) Sebastian Stan reportedly split earlier this month.
