Jessie J‘s brand-new US single “Domino” has just leaked! The 23-year-old English singer-songwriter is set to release the single for an upcoming “Who You Are” re-release. The Dr.Luke-produced pop track is fun, catchy, and perfect for radio. As always Jessie is serving some strong vocals but the track sounds a little too close to everything Katy Perry has released on “Teenage Dream.” What do you guys think??
