Blake Lively And Her 'Sisterhood of the Traveling Pants' Former Co-Stars Reunite Once Again!

Sisters stick together, and it's no different than the former cast members of The Sisterhood of the Traveling Pants. In support of their past co-star America Ferrera, at her show Lips Together, Teeth Apart, pregnant Blake Lively, Alexis Bledel and Amber Tamblyn took a selfie while reuniting at their friend's play.

"Go America!" Tamblyn captioned her Instagram photo of the three. "Supporting our girl in her play, Lips Together, Teeth Apart. #sisterhood."

As MStars News reported last month, the stars made a scene when a photo of the stars reunited over coffee.

"Always a good day when I'm with my sisters #DeLosPantalones Love these amazing women," Ferrera wrote via Instagram at the time.

Tamblyn added: "Brunch with my best bitches."

It seems Tamblyn is the one to keep an eye on. On her social media she again posted about Lively, "Finally I can share my little sister's good news!"

She captioned a photo on her Instagram of Lively's baby bump, "Congratulations my Blakey, you beautiful woman you. What a tremendous mama you are going to be."

On Oct. 6, Lively and husband Ryan Reynolds announced they were expecting their first child. She recently said, "I never knew what I wanted to do for a living, but I knew I wanted to have a lot of kids because I had come from a big family, so it was always important to me. So it's just the excitement of that finally being here."

One thing's for sure: Little Lively will have tons of doting aunts.
