In a new segment on "The Tonight Show," the pair lip-sync about every pop song out there in a "Lip Sync Conversation." While contestants usually only pick two songs in "Lip Sync Battle," Fallon and Grande's lip-sync smalltalk includes lyrics by Rihanna, Justin Bieber, Sia, Fifth Harmony, 4 Non Blondes, Zayn and more. *NSYNC even gets a shoutout when they say, "bye, bye, bye."
We finally know why "Grande" is a size at Starbucks: because we like this a latte.
"The Tonight Show Starring Jimmy Fallon" airs weeknights at 11:35 p.m. ET on NBC.
