We all know Jessie J has a super amazing soulful voice. But the singer revealed another hidden talent that will make you feel slightly uncomfortable and also kind of jealous.

JJ appeared as a guest on The Graham Norton Show, and revealed that she can SING WITH HER MOUTH SHUT.

Yep, it’s as weird as it sounds. Watch the vine for evidence of this actually happening:

Jessie said: “I discovered when I was little that I could pretend I was in a box.” This amazing talent then evolved into closed-mouth singing.

Don’t pretend you’re not impressed. We know you’re going to try singing with your mouth shut as soon as you get home this evening.
