AJ McLean of the Backstreet Boys will compete for the coveted mirrorball trophy.
McLean joins Kaitlyn Bristowe, who was the first celebrity dancer to be announced for the upcoming season. During an episode of "The Bachelor: The Greatest Seasons - Ever!" in June, host Chris Harrison surprised the former Bachelorette with the exciting news.
Former competitor and fellow Backstreet Boys singer Nick Carter had some words of encouragement for McLean. Carter came in second place back in season 21 after Bindi Irwin won the competition.
The rest of the celebrity competitors will be announced on September 2.
"Good Morning America" previously announced the pro dancers that will be competing this season. Emma Slater, Britt Stewart, Sasha Farber, Pasha Pashkov, Jenna Johnson, Brandon Armstrong, Alan Bersten, Val Chmerkovskiy, Peta Murgatroyd, Keo Motsepe, Gleb Savchenko, Daniella Karagach, Cheryl Burke, Sharna Burgess and Artem Chigvintsev will hit the ballroom for Season 29.
This season of "Dancing with the Stars" is going to look a little different, as the show will follow strict protocols to ensure the safety of the cast and crew.
"They've covered every angle -- masks, cleaning the studios, sanitizing and making sure the husband and wife people are not together because if one of us gets it that's two couples out of the competition," pro dancer Farber previously told On The Red Carpet.
