It’s not a Sisterhood of the Traveling Pants reunion unless all sisters are present. Isn’t that one of the “rules of the pants”? It's a rule that can apparently be stretched a little, at least by Blake Lively. When she met up with co-stars Alexis Bledel and Amber Tamblyn recently, Lively took it upon herself to draw in an “artist’s rendering” of America Ferrera: a heart with the initials “A.F.” inside it. Close enough!

The post also managed to reveal another new detail about the foursome, who have been real-life pals since making the first Traveling Pants movie in 2005. There's no rivalry between them and the crowd of that other famous sisterhood of the early aughts, The Divine Secrets of the Ya Ya Sisterhood. They're total ya-ya admirers.

Before we get into a fun game of “who’s the Sandra Bullock, Ellen Burstyn, Maggie Smith, etc.” of the crew, let’s dive into a bit of history of this group’s continued friendship. They have gone from fresh-faced teens to fellow moms of infants—welcoming in the new year together via Facetime, consistently showing up on each other’s social media accounts, and even protesting the Trump administration together.

The “Ya Ya A.F.” sisters might be going to a lot more Planned Parenthood protests than in the days of the traveling pants, but they’ve still got time for a good selfie. And, oh, yeah, Blake’s totally the Maggie Smith of the group.
