In late 2007, rumors circulated that Blake Lively and her 'Gossip Girl' co-star Penn Badgley were dating. In May 2008, after 'People' magazine published photos of the two kissing while on vacation in Mexico, they became more open about their relationship. Penn and Blake ended their three-year relationship in mid-September 2010.
The exes remained amicable after their split and continued shooting 'Gossip Girl' together until the CW show ended in late 2012, with a series finale that (spoiler alert) saw their fictional alter egos marry.
Here are some of their sweetest moments captured while they were together and after.
