Ariana Grande and Seth MacFarlane are Broadway ready after this ‘Suddenly Seymour’ cover on 'Carpool Karaoke'

From Ari to Audrey!

Ariana Grande and Seth MacFarlane made an unlikely pairing in the new episode of Apple Music's Carpool Karaoke, but proved they were worthy of the Great White Way.

Belting out the classic Broadway hit "Suddenly Seymour" from the musical Little Shop of Horrors, Grande, 24, and MacFarlane, 43, slayed the vocally challenging tune while driving around town.

At one point, MacFarlane even slammed on the brakes and Grande let out a "f**k!" -- but kept on key.

"We almost died, but the belting was more important," Grande declared after they'd finished the song. "I like that we didn't skip a beat. That is what comes from being a theater person. You stay in it."

Grande was clearly pleased with the outcome, posting a preview clip to Instagram.
