After six seasons, the hit CW series comes to an end in a finale that sees Penn Badgley's Dan Humphrey revealed to be the anonymous writer of the Gossip Girl blog. Meester's character, Blair Waldorf, finally gets her happy ending with on-and-off love Chuck Bass (Ed Westwick), whom she weds and eventually welcomes a son with.
Meester quietly begins dating Adam Brody, whom she met on the set of 2011's The Oranges. Coincidentally, Brody got his big start on Gossip Girl creator Josh Schwartz's previous "dramedy," The O.C. Following months of hush-hush dating, the couple confirms they are set to marry, and tie the knot during an intimate ceremony in early 2014.
