Blake Lively Had a Mini ‘Sisterhood of the Traveling Pants’ Reunion With Brown Hair — See Photos

Blake Lively comes bearing gifts!

On October 31, the Gossip Girl actor reunited with one of her Sisterhood of the Traveling Pants costars, Amber Tamblyn, to deliver a package of her newly launched line of nonalcoholic cocktail mixers, Betty Buzz. 

“This was the biggest package I’ve ever received in the mail,” Tamblyn said as she opened the large red package with Lively out of frame. “There was like a whole package and then there was like a person inside of the package, it was really weird,” she said, panning up to Lively, who was wearing a brown wig and a red sequined shawl. 

“@BettyBuzz really has outdone itself on marketing by sending me this gorgeous box of tasty refreshments and a life-size Blake Lively Halloween mannequin for my front yard,” Tamblyn wrote in the caption, adding the hashtags #HappyHalloween and #SisterhoodNerds4Ever.

Lively and Tamblyn starred alongside America Ferrera and Alexis Bledel in the touchstone 2006 Y.A. classic based on a book series of the same name. In the film, four separated best friends keep their bond strong by sharing a “magical” pair of pants that fits them all perfectly. If you know, you know. 

For many fans, seeing the friendship forged between the four costars is almost as cathartic as rewatching the classic or its 2008 sequel. “True Friendship lasts forever,” one fan commented. “And I love how 1 book turned the 4 of you into soul sisters.”
