The two stars rose to fame as the stars of their own respective Josh Schwartz-created series. Meester is best-known for playing NYC mean girl Blair Waldorf on "Gossip Girl." Meanwhile, Brody won the hearts of girls everywhere playing the a-dork-able Seth Cohen on the Cali-set teen soap, "The O.C." Meester and Brody met on the set of their 2011 flick, "The Oranges," and began dating earlier this year.
This marks the first marriage for both actors, though both have publicly dated co-stars in the past. Brody dated his onscreen girlfriend Rachel Bilson during their time on "The O.C." They broke up in 2006.
Meester previously dated "Gossip Girl" actor Sebastian Stan. "I was really sad when it ended, but that's what taught me a lot about myself and love and life -- and that's good," she said about their split.
In addition to their upcoming nuptials, Meester and Brody have multiple projects lined up. Meester lined up roles in "The Judge" and "Life Partners," the latter of which also includes her real-life future life partner, Brody. Brody's other projects include "Think Like a Man Too." He was most recently seen in "Baggage Claim" with Paula Patton.
