After nearly one month after secretly getting married Leighton Meester finally showed off her wedding ring. The former "Gossip Girl" star flashed her huge diamond while attending a press conference for her Broadway play, "Of Mice & Men."

According to Us Weekly, the 27-year-old actress joined costars James Franco and Chris O'Dowd at the Signature Theatre on Thursday, March 6th.

The gorgeous brunette looked effortlessly stylish wearing a black sweater, gray pants, and red heels all while giving photographers a glimpse of her brand new ring as she sat with her hands in her lap during the conference.

Last month news broke that Meester secretly married "The O.C." star Adam Brody in a private wedding ceremony just three months after a source confirmed that the two were engaged.

Leighton Meester has yet to publicly address her marriage or relationship with Brody however, last month the actor confirmed to a group of paparazzi that he was indeed married. The actor also flashed a simple wedding band on his left ring finger as he left the gym in Los Angeles on February 18th.

This is the first marriage for both Leighton Meester and Adam Brody. The pair grew closer after working together on the 2011 film "The Oranges" and will reunite once again on screen in the upcoming comedy "Life Partners."
