Ariana Grande took to The Tonight Show stage for the second time in two weeks on Monday night to belt out a Dangerous Woman bonus track with none other than the guy who cast her in her first Broadway musical, 13.

Jason Robert Brown joined Ariana and The Roots to perform the jazzy "Jason's Song (Gave It Away)" on Jimmy Fallon's late-night show.

After it aired, Grande tweeted that this was her "favorite performance" ever, and that the song truly shows what her voice can do.

Early in the evening on the show, Fallon did a skit with Grande's pal Miley Cyrus, playing sixth-grade girls in "Ew!"

On Ari's last show with Fallon, she announced the dates to her Dangerous Woman Tour.
