Ferrera kicked things off by posting a selfie of herself grinning from ear to ear.
“On my way to live out a childhood fantasy with one of my besties @amberrosetamblyn— what kinda madness are we getting ourselves into?” wrote Ferrera in the caption.
Meanwhile, Tamblyn commemorated the occasion by posting a cute photo of herself and Ferrera posing with host, LL Cool J. The rapper must have made quite an impression on the ladies, because Tamblyn even joked that they had decided to induct him into the sisterhood.
“So excited to announce the newest sister to the ‘hood @llcoolj,” wrote Tamblyn. “Maybe, just maybe, we did #LipSynchBAttle today and maybe we just killed it @americaferrera.”
There’s no word yet on when Ferrera and Tamblyn’s episode of Lip Synch Battle is expected to air, but we’ll definitely be tuning in whenever it does!
Lip Synch Battle season 3 is set to premiere sometime in 2016 on Spike.
