Stars of the Young Adult world have descended upon the French Riviera for the ultra glamorous Cannes Film Festival. Blake Lively has clearly taken a cue from her "Gossip Girl" alter ego -- fashion queen bee Serena van der Woodsen. Lively has been stunning with her looks all week, including her appearance the other day at hubby Ryan Reynolds film "The Captive." Also bringing their A-game has been "The Hunger Games" cast and newbie Young Adult author and reality television teen Kendall Jenner.
