On Monday (May 6), Ariana Grande played her first of three nights during the Los Angeles stop of her Sweetener tour, and there was a very special guest at The Forum: Jungkook. After the concert, the BTS singer posted a thoughtful message to the group's Twitter.

"I felt and learned a lot after seeing her stage," he wrote alongside a selfie of him holding up a "7 Rings" dollar bill. "I am really challenged by her stage and will try harder! #ArianaGrande"

Meanwhile, the woman he was praising was stanning over the Korean pop star. "screaming," Ari captioned a photo of her and Jungkook on Instagram. "thank u soooooo much for coming to my show, Jungkook. it meant so much. love u sm" But that's not all. She also shared a screenshot of her lockscreen on her Instagram story, showing she had changed it to a black and white version of the same photo (we can only imagine how many ARMY members and Arianators did the same thing).

The singer is also scheduled to perform tonight (May 7) and Thursday (May 10) at The Forum in LA. We can only imagine what other celebrity fans will be making appearances at those shows.
