Brooklyn Nine-Nine and One Day at a Time are about to have the coolest crossover EVER!

Okay, okay... it's not technically a crossover, but we will get to see some familiar Brooklyn Nine-Nine faces appear on One Day at a Time next year. Melissa Fumero and Stephanie Beatriz announced via Twitter this morning that they'd both be guest starring in Season 3 of Netflix's family comedy!

"Guess who's coming to hang with the Alvarez family!?!! @iamstephbeatz & I are guest starring on @OneDayAtATime Season 3!!!!!!!" Fumero wrote. She even posted a cute boomerang video of herself and Beatriz in the Alvarez house.

Beatriz retweeted the video adding, "CAN NOT EXPRESS HOW EXCITED WE ARE! @everythingloria thank you for welcoming us. We're having so much fun this week on the @OneDayAtATime set!"

Executive producer Gloria Kellett confirmed the news on Instagram, posting a photo with Fumero and Beatriz with the caption, "That's right! The @brooklyn99fox ladies are in the casa!! Over the moon to welcome @iamstephbeatz & @melissafumero to the Alvarez familia!! It's gonna be an epic episode!!"

According to TV Line, the two actresses will play cousins of Penelope (Justina Machado).

One Day at a Time will return in 2019.
