The daytime TV personality stopped by Wednesday’s Tonight Show, where she and Fallon took turns lip-syncing for judge Justin Timberlake.
DeGeneres performed a comically downbeat version of Diana Ross’ “Do You Know Where You’re Going To,” which involved the comedian writhing around on the stage floor.
She followed that up with a strident display of Rihanna’s “Bitch Better Have My Money,” which ended with an epic mic drop.
For his part, Fallon performed a mid-2000s rock hit and a 2015 club banger, the latter of which allowed him to do a lot of wacky dance moves.
Despite his lip-sync prowess, it became evident that Fallon was worried about DeGeneres having the upper hand, with Fallon even slipping money to Timberlake after performing his first tune.
“Whoa, what is this?” Timberlake asked when he saw the cash; Fallon replied: “Take care of yourself — don’t worry about it.”
