Hey there, gossip-hounds. You'll be happy to know that tongues were wagging on November 22, when Gossip Girl star Leighton Meester rocked her high-fashion walk over to hit musical Rock of Ages at Broadway's Brooks Atkinson Theatre. We're not sure whether Meester sang along to the mix-tape classics that have made the show one of the most popular on the Broadway strip (though she's got a solo album out, so she shouldn't be shy!), but we do know the queen bee of the CW series was cavorting backstage with the '80s-chic cast post-show, rubbing elbows with stars Constantine Maroulis, James Carpinello, Mitchell Jarvis, Lauren Molina and more! Then, once she got "High Enough" with the extroverted cast, Meester gave us her best "xoxo" and kissed the show goodbye. Click on to catch the Gossip Girl star at Rock of Ages.
