It’s been eight years since the last Sisterhood of the Traveling Pants movie, but that hasn’t stopped the cast members from remaining as close as their on-screen counterparts. America Ferrera and Amber Tamblyn provided the latest example on Sunday, when the two used Instagram to tease their upcoming face-off on Lip Sync Battle.

“On my way to live out a childhood fantasy with one of my besties,” Ferrera wrote.

In a second post, she said, “Can’t wait for you guys to see the craziness that went down!! @amberrosetamblyn Slayed me dead! #lipsyncbattle #duelingsisters.”

Tamblyn posted a photo as well, featuring her and Ferrera posing with Lip Sync Battle host LL Cool J. “So excited to announce the newest sister to the ‘hood,” Tamblyn wrote.

No word yet if the other half of the Sisterhood, Blake Lively and Alexis Bledel, will make an appearance.

Season 3 of Lip Sync Battle is expected to premiere later this year on Spike.
