Paula Deen and Gary Busey (who made his announcement on a horse last night) were the latest celebs to be revealed for this season's Dancing With the Stars roster, but there's an even newer entry who only recently became a star: Alek Skarlatos, one of the three American heroes who foiled a terror attack on a Paris train last month, the AP reports. The 22-year-old Army National Guard Specialist, described by ABC as "an avid painter and military history buff" who plans on joining the police force, will compete when the show kicks off its 21st season on Sept. 14. See the full cast list on ABC. (More Dancing with the Stars stories.)
