Blake Lively and Ryan Reynolds Pictures at Amber Tamblyn and David Cross Wedding

Blake Lively and her husband, Ryan Reynolds, were among those who travelled to upstate New York over the weekend for Amber Tamblyn and David Cross' wedding. Amber and Blake have been pals since their Sisterhood of the Traveling Pants days, and their other two co-stars, Alexis Bledel and America Ferrera, also travelled to the nuptials, along with famous friends like Amy Poehler and Questlove, who Instagrammed pictures from the busy weekend.

Amber wore a yellow dress and went shoeless for her big day. Amber, 29, and David, 48, had Yo La Tengo as their wedding band, with Questlove as the DJ. It was Amber's turn to have the spotlight after the Traveling Pants gang attended Blake and Ryan's South Carolina wedding just last month.
