The upcoming season of “Dancing With the Stars” will include a teenage conservationist, a champion jockey, a boy band member and now a teenage Vine star.

Hayes Grier, 15, was announced today as the latest celebrity to join the reality TV competition’s roster for the show’s 21st season.

The show tweeted the news this morning, directing fans to follow the social media-savvy teen on Vine and Twitter.

Hayes, of North Carolina, shot to fame with his videos and now has 4 million followers on Vine and Instagram.

The teenager naturally made his own “DWTS” announcement by releasing a video early this morning.

Hayes later tweeted, “I’m going to go back to bed right now since I have my first rehearsal in a few hours. Keep the hashtags going and trending ! Be back soon”

Hayes is the fourth announced celebrity who will compete on this season of “DWTS.” Bindi Irwin, the 17-year-old daughter of the late “Crocodile Hunter” Steve Irwin, will also join the celebrity cast, as well as American Pharaoh jockey Victor Espinoza and “Backstreet Boy” member Nick Carter.

More of the new celebrity cast will be revealed on “GMA” Wednesday, Sept. 2. The new season of “Dancing” premieres at 8 p.m. ET Monday, Sept. 14, on ABC.
