Ariana Grande makes a surprise stop on 'The Late Late Show'

Terence Patrick/CBSAriana Grande made a surprise visit to The Late Late Show with James Corden Tuesday night, much to the delight of some unsuspecting guests.

Ariana came out unannounced and sang with the TNT Boys, an adorable boy band trio from the Philippines who previously performed at James Corden‘s other hosting gig, The World’s Best. The boys were so floored by the moment they could barely get through their rendition of “And I Am Telling You I’m Not Going” as Ariana sang along.

Afterward, Ariana chatted with Corden about her history-making day, becoming the first artist to simultaneously hold the #1, #2 and #3 spots on the Billboard Hot 100 since The Beatles did it in 1964.

“I thought it was hilarious. When I woke up I thought it was like an edit, like that my fans made,” Ariana told Corden, echoing her reaction on Instagram earlier in the day.

Once reality set in, the “7 Rings” singer said she drove around listening to The Beatles with her mom. Ariana apologized multiple times during the chat, describing the experience as “crazy,” even promising to take a break and “go away for a little, I promise.”

Asked what she planned to do to celebrate such a milestone achievement, Ariana confessed she doesn’t have much of a personal life these days.

“Well, honestly, I was so excited you asked me to do this today cause I usually don’t have anything to do, other than just make songs and, like, rehearse and that’s it,” she declared, adding, “personal life still non-existent.”

Ariana of course famously ended her engagement to Pete Davidson late last year, and addressed him and other past loves in her current #3 hit — formerly #1 — “thank u, next.”
