Someone is ready for his six seconds of fame. Hayes Grier, who is apparently a Vine star, has been revealed as the latest contestant who will compete on Dancing with the Stars season 21. Grier is just 15-years-old, making him the second-youngest contestant ever (Willow Shields from last season was the youngest at 14).
