Victor Espinoza to join 'Dancing with the Stars' season 21 cast

It was announced on Tuesday that Triple Crown-winning jockey Victor Espinoza will be the latest to join the Dancing with the Stars season 21 cast.

Bindi Irwin, the 17-year-old daughter of "Crocodile Hunter" Steve Irwin, will also be dancing.

The Mexico-born Espinoza won the Triple Crown in 2015 while riding on the horse American Pharoah. Prior to Espinoza's win, the last time the Triple Crown feat had been accomplished was in 1978.

ABC has also announced many of the professional dancers that will join the show this season, and fans will recognize some familiar faces.
