WARNING: Spoilers Below! Well, first off, this girl can sing. Like sing-sing. We’ll get used to the insane amount of talent in these young’uns at some point, but for now, we’re still impressed that Dinah is barely 15 years old. If you saw any of the X Factor promo videos, you probably noticed a girl featured prominently with red streaks in her hair — That would be Dinah Jane Hansen.
