BEAK TWEAK Blake Lively, before (l.) and after (r.)
Hey Upper East Siders! Gossip Girl here with a pop quiz: Which cast member had a bit of discreet work done on her nose before the show started filming?

That would be Blake Lively, the soignée blonde who plays reformed bad girl Serena van der Woodsen on the hit CW show, which chronicles the debauched lives of a coterie of attractive, white New York City prep school kids. (It’s a hit in terms of “buzz,” if not ratings.)
