What happens when Tiffany Haddish and Jimmy Fallon face off in a lip sync battle? Grad A prime entertainment, that's what. 

The Nobody's Fool star recently appeared on The Tonight Show Starring Jimmy Fallon and participated in one of the show's most famous skits, AV Club reports. 

Fallon started pretty strong, singing the classic bop, "Groove Is in the Heart" by Deee-Lite.

That's when Haddish came with the heat and lip-synched to Lady of Rage’s “Afro Puffs.”

The Roots even had to jump in and sing along with her because she was so hype. 

So, with Haddish being like, "CHALLENGE!," Fallon had to bring his A-game. He came out syncing "Psycho" by Post Malone, equipped with the face tattoos and everything. 

Haddish followed that by taking an opportunity to prove she doesn't always say "She ready!" for nothing.

The comedian requested a whole black and white filter and showed off her lip-synching and dancing skills in a rendition of James Brown's "Sex Machine." She even draped herself with the classic Godfather of Soul cape.

We're not biased or anything, but, um … she won.
