Ariana Grande Has Crazy Lip Sync Conversation With Jimmy Fallon (Video)

Forget battles, this pair have a friendly chat with the help of 4 Non Blondes, Justin Bieber and even Frank Sinatra on Monday’s ”Tonight Show“

“Lip Sync Battles” are so last week.

Jimmy Fallon has now progressed to having “Lip Sync Conversations,” which he smoothly demonstrated with Ariana Grande on Monday night.

The bubbly pop star and “The Tonight Show” host had a full chat with the help of lyrics from 4 Non Blondes, Mike Posner and many other artists.

After Grande asked Fallon “Hey, what’s going on?” he replied sheepishly: “I took a pill in Ibiza to show Avicii I was cool.”

The chat inevitably turned to social media, with the pair using Frank Sinatra, Major Lazer and Twenty One Pilots’ lyrics to describe their throwback Instagram photos.

But when Fallon got a bit snappy with his former Nickelodeon star guest, he was forced to channel Justin Bieber and ask: “Is it too late now to say sorry?”

See the wonderful mashup above.

“The Tonight Show” airs at 11:35 p.m. on NBC.
