Leighton Meester and Adam Brody Secretly Married

What?  No warning from Gossip Girl?  Actors Leighton Meester and Adam Brody had kept their wedding plans quiet since becoming engaged three months ago, and that plan seems to have worked.  Reports say the couple was able to dodge the watchful paparazzi eye and say 'I Do' on the down low.

The stars, rumored to have wed in a secret ceremony, were seen just days ago vacationing at Mexico's St. Regis Punta Mita Resort, and Leighton reportedly recently had her bachelorette at West Hollywood restaurant Hamburger Mary's, according to E! News.

The 27-year-old actress, who portrayed Blair Waldorf for five seasons on Gossip Girl, and the 34-year-old O.C. actor got engaged in November, after only nine months of dating. The pair have remained famously private, never officially confirmed they were an item.

This is the first marriage for both stars. Meester was previously linked to actor Sebastian Stan, while Brody dated his O.C. costar Rachel Bilson for many years while they appeared on the series.
