The Sisterhood is adding a new member.

It's been 12 years since the Sisterhood of the Travelling Pants first hit cinemas. America Ferrera, Alexis Bledel, Blake Lively and Amber Tamblyn starred in the dramedy, which follows four best friends who are spending the summer apart for the first time ever - but remain connected through a really, really great pair of jeans which they decide to share. And since the movie first premiered, the actresses have remained incredibly close, regularly reuniting on the red carpet (or in their day-to-day lives) to celebrate some major milestones. https://www.instagram.com/p/BHny2j5A36C/ Which makes their most recent get together all the more sweeter. America Ferrera announced on New Year's Day that she was expecting her first child with an adorable Instagram post - and it didn't take long for her Sisterhood to show up with well wishes. She shared a photo on Tuesday that showed all four of the actresses cuddled up on a couch, with her castmates placing their hands on her blossoming baby bump. She captioned the photo:

"Starting the New Year off with blessings from my Sisterhood. We've got work to do for the next generation. Let's get to it. #TIMESUP."

The 33-year-old Superstore actress is the most recent of her co-stars to become a mum. Blake shares two daughters, Ines, 1, and 3-year-old James, with her husband Ryan Reynolds; Amber and her husband David Cross have a 7-month-old daughter named Marlow; and Alexis shares a two-year-old son with her husband Vincent Kartheiser.
