Here is one Gossip Girl that appears to have grown-up overnight. Blake Lively, accompanied by her boyfriend Penn Badgley, steamed up the red carpet. Taking a leaf out of Cindy Crawford's book, Blake chose this blue chiffon Versace gown, featuring one-shoulder neckline and a thigh-high split. I love the simple pulled back hair, smoky make-up and subtle all-over glow. Sexy but not overtly so.
