When Ariana Grande superfans were least expecting it, the pop superstar surprised them with a visit when they thought they were simply filming fan cover songs!
The Tonight Show starring Jimmy Fallon set up the surprise when Ariana visited his show this week, and not surprisingly, everyone freaked totally out.
During the interview, the 24-year-old singer also announced her new record, Sweetener, will be coming out this summer and explained the strange connection between Ariana and her grandfather's friend who was a co-writer on the original song she covered for the album's intro song, "Raindrops."
After being out of the spotlight for nearly a year – Ariana came back full force on Fallon!
