Ariana Grande was a guest on The Tonight Show starring Jimmy Fallon on Friday.

The pop star was on hand to appear in an “Ew” skit with the host before joining him for what the singer revealed is her first sit-down interview on a talk show.

“I’m so nervous,” said Grande. “I don’t speak; this is my first time speaking in front of people. I’ve never talked on a talk show. I feel vulnerable, I feel so weird.”

Fallon calmed the pop star down with his easy going manner, even managing to convince Grande to perform her impression of Celine Dion.

Grande’s second album, “My Everything”, continues to dominate the charts with four singles issued to date; the record currently sits at No. 20 in the US Billboard 200 album chart.
