Penn Badgley and Zoe Kravitz took their romance public once again today as they went on a walk in the Big Apple. The couple held hands as they strolled the streets, and Penn didn't go unnoticed by a group of Gossip Girl fans, who flagged him down as they walked by. Zoe patiently waited on the sidewalk while he stopped to take some photos with them. Zoe and Penn haven't spoken out publicly about their relationship, but Zoe did attend the recent premiere of Penn's new film Margin Call, and the pair also were spotted kissing in Manhattan earlier this month. Before she and Penn were an item, Zoe was frequently spotted out with her X-Men: First Class costar Michael Fassbender. Previous to linking up with Zoe, Penn took some time to live the single life, having split from his girlfriend of three years — Blake Lively — last October.
