There isn't much that is more attractive than a gorgeous girl playing and singing a song like an angel. That is a scientific fact. However, like the sirens in Greek mythology, a girl like this can also be very dangerous, luring men in with her enchanting music and voice, and making us do dumb things. But that's a risk we're willing to take with our weekly feature of hot girls playing and singing hit songs for your enjoyment. This week's cover of "Genie in a Bottle" by Christina Aguilera comes from Katie Carson. Try not to fall in love.
