The singer also played a friendship game with Jimmy Fallon.

Ariana Grande had a very busy night on Thursday (Sept. 8) when she dropped by The Tonight Show to sing, play a game and share a secret. One of the first orders of business was announcing her Dangerous Woman Tour, with Ari saying, "I'm very excited, I can't wait to get on the road again." The 36-date tour will launch on Feb. 2 with a show in Phoenix, Arizona and currently runs through an April 15 gig in Orlando, Florida, with stops in-between in Nashville, New York, Boston, Toronto, Chicago, Seattle, Denver and Miami; more dates will be announced soon.

Grande also performed, digging into her island-flavored bump-and-grind single "Side to Side" with the Roots, and even filling in for an absent Nicki Minaj on the feature.

She didn't stop there, plugging her upcoming role in NBC's Hairspray Live! and her part in the upcoming animated comedy Sing, where she's featured on the soundtrack with the Stevie Wonder collabo "Faith." As you might expect, she kind of lost her mind working with the music icon. "I'm featured on a Stevie Wonder song, man! That's like, what?" Grande said. "I'm done now, I'm good. That's it for me."

Sure, getting to sing together was amazing, but Grande said just toe-to-toe with Wonder at the mic was a marvel. "Not only did I get to sing with him, but we were in the same booth, so it was like, me and Stevie Wonder arm-in-arm, holding hands in the booth, singing together, laughing, having a good time," she said. "Every time I got comfortable with the fact that I was in a booth, arm-in-arm with Stevie Wonder, he would hit a Stevie run, and I'd be like, 'Oh, s--t, that's Stevie Wonder.’"

Lastly, Grande and host Jimmy Fallon also put their relationship to the test with the Best Friend Box Challenge, where they had to guess personal details about one another. Spoiler alert: they don't know each other at all.
