"I had a little heartbreak not being able to a part of the 10th anniversary, the 20th season. It's such a huge milestone for 'Dancing With the Stars.' It's my family, so I wanted to be a part of it. ... I'm so glad we made it happen. Let's make it the best season ever," Hough said to "GMA" from New York.

Another inspirational celebrity participant is Noah Galloway, an Army veteran. He lost his left leg and left arm above the elbow in a bomb blast. He is paired with Sharna Burgess.

Alfonso Ribeiro, winner of Season 19, gave some advice. "It's not about winning week one, it's about winning that final week. You've got to take it slow, pace yourself. Go hard, learn everything, and be the best you can be and give it 100 percent, but pace yourself." Ribeiro also said that "it is a marathon, not a sprint."

"Dancing With the Stars" airs March 16, 2015 on ABC.
