Blake Lively Reunites With 'Sisterhood Of The Traveling Pants' Co-Stars

Blake Lively and her "Sisterhood of the Traveling Pants" co-stars reunited, proving that their onscreen friendships are just as solid in real life.

Amber Tamblyn uploaded a photo with Lively, Alexis Bledel and America Ferrera to her Instagram Monday. In the snapshot, the four ladies pose with big smiles, looking like not a day has passed since they appeared together in the 2005 film adaptation of the popular young-adult novel.

"Brunch with my best bitches. #sisterhood," Tamblyn wrote. Ferrera reposted the photo, writing: "Always a good day when I'm with my sisters #DeLosPantalones Love these amazing women."

In April, Us Weekly reported Alloy Entertainment plans to develop a third installment in the series based on author Ann Brashares' fifth and final "Sisterhood" novel, "Sisterhood Everlasting." Following 2008's "The Sisterhood of the Traveling Pants 2," the third film will take place years later, showing the girls as young women who have grown up and fallen out of touch.

"The 'Sisterhood' series is one of Alloy’s most cherished properties and we are looking forward to continuing its legacy with 'Sisterhood Everlasting' nearly a decade after the first film was released," Alloy Entertainment President Les Morgenstein said in a statement. "The original film brought together an incredible group of talent who we hope to unite for fans once again."
