Texas native Chace Crawford gets his big break playing the guy in the Serena-Blair love triangle on Gossip Girl. He stars as Nate Archibald, a privileged lacrosse player and Blair’s boyfriend.

Crawford fits right in at the CW, a network with a history of ridiculously good-looking casts.Jim Spellman/WireImage.com - Wednesday, August, 29, 2007, 12:29 AM
