Ariana Grande Was ‘Screaming’ Watching BTS Rehearse: ‘Most Incredible Thing I’ve Ever Seen’

Welcome to the BTS A.R.M.Y., Ariana Grande! On Monday night (Jan. 27), the superstar took to Twitter to gush about her love for the K-pop sensations. 

Replying to a video of RM mentioning her during an interview on the Grammys red carpet, Grande tweeted, "Honestly…… i was able to watch them rehearse for something and it was the most incredible thing i've ever seen. i'm not kidding. i was screaming. i couldn't stop talking about it / still cant."

The rehearsal Grande referenced in her tweet was likely for the boy band's star-studded Grammys performance of "Old Town Road" alongside Lil Nas X, Billy Ray Cyrus, Diplo, Mason Ramsey and Nas; the artists ran into each other backstage and took an internet-shattering pic together.

Oh, and the feeling's mutual — RM told Billboard on the Grammys carpet that they'd love an official collab with the "7 Rings" singer. "We always want to collaborate with Ariana, she’s the one right now and she’s the best," RM said. "Please collaborate with us, Ari!"

BTS is also currently prepping the live television debut of their latest single "Black Swan," which they're set to perform Tuesday night (Jan. 28) on The Late Late Show with James Corden.
