Adam Brody and Leighton Meester managed to do the impossible and keep their 'celebrity' wedding a secret.

It has only been three months since the pair's engagement became public knowledge, and now they have tied the knot, Us Weekly reports.

The newlyweds were most recently spotted in Mexico's St. Regis Punta Mita Resort over the Valentine' Day period, which occurred just a couple of weeks after Meester had her bachelorette party at famous West Hollywood hangout Hamburger Mary's, according to E!News.

Maybe this implies their wedding ceremony or honeymoon could have taken place during their vacation to south of the border.

This is only strengthened by the fact that Brody was spotted wearing a ring on his left hand when they arrived back in the US. Speculation aside, the couple, who are known to be very private, have yet to comment on the status of their relationship.

Brody and Meester met on the set of 'The Oranges' in 2011 and began dating in February of last year (2013).

Their private nature could be down to the fact that they both have had public relationships with fellow actors in the past, which didn't work out.

Brody was in a 3 year relationship with his 'O.C' co-star, Rachel Bilson, until they broke up in 2006.

Meanwhile, Meester previously dated 'Gossip Girl' actor Sebastian Stan and when they split in 2010, she told Seventeen, "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."

This is the first marriage for the both of them.

Congratulations!
