Leighton Meester wore Vera Wang and posed with the designer at the launch of Vera's Lovestruck fragrance at Harrods in London today. The Gossip Girl actress is the face of the new scent, and Leighton kicked off work for Vera Wang with a photo shoot in NYC last November. She got similarly glamorous at Sunday's MTV Movie Awards, where she donned a sparkling Balmain mini on the red carpet. Leighton will continue to stay in the spotlight as she ramps up promotions for Monte Carlo, which comes out in July. First, though, she'll take the stage to perform a sold-out show at LA's Troubadour club with the band Check in the Dark on June 13.
