Well, it's not the Sisterhood of the Traveling Pants 3 movie news we've been waiting for, but this reunion is quite possibly the next best thing!

While stars are busy filming the new season of Lip Sync Battle, a sneak peek at one of this season's girl-power duos is everything our '05 selves want and need.

Sisterhood stars America Ferrera and Amber Tamblyn teased their Lip Sync Battle collaboration on Instagram this weekend. "On my way to live out a childhood fantasy with one of my besties @amberrosetamblyn—what kinda madness are we getting ourselves into?" Ferrera mysteriously captioned a selfie on Saturday.

Tamblyn then took to the social media platform to confirm their appearance on the Spike show with a selfie of her and the Ugly Betty actress with host and "new sister" L.L. Cool J.

She captioned the shot, "So excited to announce the newest sister to the 'hood, /@llcoolj. Maybe, just maybe, we did #LipSyncBattle today and maybe we just killed it @americaferrera."

Now, if only Traveling Pants co-stars Blake Lively and Alexis Bledel make a special guest appearance on the episode, our lives would be complete!
