Jessie J Sings "Bang Bang" With Her Mouth Closed—And You Can Still Understand Every Word! Watch the Video

Jessie J, you impossibly talented woman, you!

Last week, the "Bang Bang" singer, whose massive collab with Nicki Minaj and Ariana Grande has just been nominated for a Grammy (for Best Pop Group Performance), visited The Graham Norton Show, where she revealed a hidden talent: She can sing (and still sound totally intelligible) with her mouth closed.

"Well, when I was younger, I used to do auditions all the time, and I was asked what I can do. And I discovered, when I was little, that I could pretend I was in a box," the British singer told Graham, then laughed, explaining, "I was a lonely child!"

The pop songstress, 26, said that soon after, she discovered she could also do the "trapped in a box" trick while belting out her favorite tunes. The British TV host asked her to demonstrate with a "boxed" rendition of "Bang Bang." The rest can only be truly appreciated by watching the video above. Enjoy!
