Another celebrity has been booked for Dancing with the Stars Season 21.
Although we may need to use that term loosely this time around.

Beloved Vine sensation Hayes Grier has been cast on the upcoming season of this ABC competition – and while his name may not be familiar to everyone, it’s familiar to quite a large contingent of Internet users.
Grier has over four million followers on Vine, making him one of the most popular posters on this video service.
He also has over three million Twitter followers and he announced the DWTS news himself to them thusly:
“Start tweeting and retweeting #hayesdwts @DancingABC Love all of you who helped me get here. Go give the video a thumbs up and respond."
He later added:
"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."
Grier joins a Dancing with the Stars cast that include Triple Crown-winning jockey Victor Espinoza; daughter of the late Steve Irwin, Bindi Irwin; and occasional racist, Paula Deen.
The new season kicks off on September 14 and the full cast will be announced on Good Morning America next Wednesday.
