 Army National Guard Specialist Alek Skarlatos has joined the Dancing with the Stars Season 21 cast! Alek became a worldwide hero in August when he helped avert a massacre aboard a Belgian train. While on vacation after a deployment in Afghanistan, the 22 year-old sprang into action when an armed attacker began shooting on the train. Alek and two of his friends, Airman 1st Class Spencer Stone and student Anthony Sadler, disarmed and subdued the attacker, who was armed with guns and a box cutter. The California native is an avid painter and military history buff. In between National Guard deployments, Alek studies at a local community college and plans to enter the police force. See Alek hit the dance floor on the Season 21 Premiere of Dancing with the Stars, MONDAY SEPT 14 8|7c on ABC.

 What better way to announce that Gary Busey will appear on the forthcoming season of Dancing With the Stars than by having Busey ride a horse out onto Jimmy Kimmel’s late-night stage? No better way, apparently: that’s how Busey was revealed as the competition show’s ninth contestant on Tuesday night. 
 
 “I am so proud to be here with you,” Busey said to Kimmel. “To announce this incredible, [life]-changing thing.” When Kimmel asked why Busey decided now was the time to join Dancing With the Stars, the actor replied, “I didn’t have anything else to do.” Busey then rode his horse off the stage. 
 
 This season of Dancing With the Stars is set to include Andy Grammer, Chaka Khan, Victor Espinoza, and Vine star Hayes Grier, among other contestants. (Busey’s horse will not participate.)
