Earlier tonight at London's iTunes festival, an awestruck Jessie J brought out her idol Brandy to duet with her on their empowering anthem 'Conquer The World'. On that same day, Jessie released her sophomore album 'Alive' in the UK, so why not celebrate it in a big way? Both ladies belted their asses off during their parts but there was nothing narcissistic or competitive about their delivery. They gave each other supportive glances, nodding approvingly when the other wasn't singing. Plus, Jessie looked like she couldn't quite believe it. Such a moving moment. Let's just keep our fingers crossed and hope they release this as a single at some point.
