Last night, Sebastian attended the American Eagle Outfitters Times Square Flagship Store Grand Opening Party. Where his girlfriend Leighton Meester was performing. A lot of the pictures i’ve added to the gallery feature Leighton on stage, if you look to the side of the picture – you can see Sebastian (looking so cute as he’s cheering and smiling at Leighton! It’s adorable!) and Michelle Trachtenberg standing at the side of the stage.
