Ariana, who's been busy preparing for her performance at the 62nd Grammys, happened to spot BTS during one of her rehearsals and posted a photo with the group on Instagram.
"Looked who I bumped into at rehearsal," Ariana captioned the photo.
A self-confessed Ariana Grande fan, Yeri commented, "I envy them, Ari," to which Ariana responded, "Can't wait to hug you one day."
It must have been an ultimate fangirl moment for Yeri! Aww.
"Yeri" was a trending topic on Twitter as fans reacted to the two artists' adorable Instagram exchange.
