BREAKING: Another real-life GG breakup. Leighton Meester (Blair) and her boyfriend Sebastian Stan (Carter) have reportedly called it quits. So who did the dumping and who was left crying? Apparently it's Leighton who made the break.
Though the part of Cap went to Chris Evans, Gossip Girl's favorite bad boy (and Leighton Meester's paramour) so impressed the flick's casting team that they offered him the part of Bucky Barnes, Captain America's plucky orphaned sidekick.
