Amber Tamblyn and Blake Lively, who starred together in Sisterhood of the Traveling Pants, were reunited Monday to support and watch costar America Ferrera’s debut on Superstore.

Blake Lively later posted a pic of the twosome for fans on Instagram, as reported by Entertainment Weekly.

The girls seem to be fast friends for life. Earlier this week, Tamblyn posted throwback pictures of Lively and Alexis Bledel, plus a real-life reunion with Ferrara.

While fans continue to clamor for a big-screen reunion of the sisterhood, it is unclear if it will become a reality. However, Ferrara did tell People magazine in January 2015 that a third Sisterhood of the Traveling Pants film was “very much in the works.”
