Actress: Blake Lively
I have loved Blake Lively ever since her big debut in "Sisterhood of the travelling pants" (Love that movie), and still do in her role on Gossip Girl as "Serena VanderWoodsen".
She looked stunning in this Zuhair Murad gown this week on the show.
I think she is a natural beauty who looks great no matter what. I love that she can pull off a gorgeous gown, but yet still dresses casual during time off.
