Hayes made the big announcement in a new video and started tweeting about the upcoming journey almost immediately.
He even revealed that rehearsals are beginning soon. Like, REALLY soon.
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 Grier (@HayesGrier) August 27, 2015
He also posted an Instagram pic of his dancing shoes and got the tiniest bit emotional while speaking to his fans in the caption. "But I just wanted to take this moment to thank you guys for getting me here and hope you will be supporting me through this journey," he wrote. "I'm excited and nervous as this will be my biggest challenge! And I want you to be part of it al!"

Meanwhile, rumors are currently swirling that Hayes' brother Nash Grier is also going to be joining the season 21 cast. While we can't yet confirmed, we have to admit, it'd be pretty amazing to see two brothers pitted against each other in the popular dance competition! (And just imagine all the behind-the-scenes vlogs!)
