Jessie J's Bang Bang is another one of my absolute favorites right now. It's such a good dance song and you can't help but sing the catchy lyrics. I can't wait to see what they decide to do with the video. Until then, watch Jessie J sing it acoustically, sans Ariana Grande and Nicki Minaj, on the Elvis Duran and the Morning Show. You wouldn't think it would sound good with just a guitar, but it does! Check it out!
