Finally! Nearly one month after secretly tying the knot, Leighton Meester showed off her wedding ring while attending a press conference for Broadway's Of Mice & Men.

The 27-year-old actress joined costars James Franco and Chris O'Dowd at the Signature Theatre on Thursday, March 6. Looking stylish in a black sweater, gray pants, and red heels, the newlywed gave a glimpse of her brand new ring to photographers while sitting with her hands in her lap during the conference.

Us Weekly exclusively revealed last month that the Gossip Girl star secretly married O.C. alum Adam Brody. The couple tied the knot in a private wedding, just three months after a source confirmed to Us that the twosome was engaged.

While Meester hasn't spoke publicly about her relationship with Brody, the actor confirmed last month that he was, in fact, married when questioned by a photographer. He also showed off a simple wedding band on his left ring finger while leaving a gym in L.A. on Feb. 18.

This is the first marriage for both. Meester and Brody worked together on the 2011 film The Oranges, and can be seen together again on screen in the upcoming comedy Life Partners.
