Newlywed Blake Lively brought her husband Ryan Reynolds to Sisterhood of the Traveling Pants co-star Amber Tamblyn's wedding to Arrested Development actor David Cross, marking their big debut as a married couple!

The A-list pair, along with guests Amy Poehler, Jason Ritter, and America Ferrera among others, were in attendance as the bride, wearing a canary yellow dress, arrived via canoe to the nuptials.

The Gossip Girl star and her Safe House actor beau tied the knot in an intimate South Carolina ceremony Sept. 9, but we've yet to see them step out as husband and wife until now.

What an adorable duo!
