With just a boombox and a camera man, Jessie J performed “Who You Are”, the title track from her upcoming album, to a growing crowd on the underground in New York’s Time Square.

“Performing is where I feel most comfortable, and I love the reaction of people,” said Jessie. “Some people might put their fingers in their ears, some people love it, some people cheer, some people leave. And it’s good, it’s nice. I like honest reactions, and that’s what I think I’m getting.”

The rising star performed at tonight’s BRIT Awards nomination party in London, and was recently announced as the BRIT Awards’ Critics Choice Award winner.
