It’s been seven years since the last Sisterhood of the Traveling Pants movie, but the sisterhood bond is still strong. Amber Tamblyn and Blake Lively reunited Monday to watch costar America Ferrara’s debut on Superstore, and took the opportunity to Instagram about it.

This isn’t even the first time the sisters have been in a nostalgic mood. Earlier this week Tamblyn posted throwback pictures of Lively and Alexis Bledel, plus a real-life reunion with Ferrara.


The possibility of a big-screen reunion of the sisterhood remains unclear, though Ferrara did tell PEOPLE in January 2015 that a third Sisterhood of the Traveling Pants film was “very much in the works.”
