Leighton Meester lights up the Gossip Girl set as she films a new scene in Brooklyn, New York on Wednesday morning (September 14).

The 25-year-old actress pulled together her look with a whistle and looks like she’s putting Blair’s potential bridesmaids through the ultimate test!

Leighton recently chatted with EOnline about her dual career in music and acting and revealed she could never choose just one. “Both is where it’s at. If I had to choose, I think I’d be very unhappy.”
