After all her alleged seething backstage at the recent Saturday Night Live over Kirsten Dunst being with her ex, Justin Long, Drew Barrymore ended up in the arms and on the lips of perpetually vested Gossip Girl throb Ed Westwick at the show's afterparty and a party after that. And last night they were spotted in a "full-on make-out session" at the Kings of Leon concert at Webster Hall. Barrymore is now officially a serial dater and, at 33, a cougar; Westwick may look 35 on Gossip Girl, but he's only 21. (Photo: Justin Bishop/Courtesy of Vanity Fair)
