"I've never trained with a deaf person before, so it's a whole new ball game for me," she said. "Being a teacher, I have to really find out different teaching methods to be able to overcome this, and so far we're going really well."
One person who doesn't seem nervous at all is the America's Next Top Model winner. In fact, DiMarco is excited about how quickly he's learning to dance.
"Actually, my dancing feet are pretty good," he told ET via his interpreter on the orange carpet. "I'm pretty surprised and pretty impressed, because I've never danced before. I also have a great teacher!"
"It's not exactly what I expected," the 26-year-old model added. "I thought that I would struggle a lot and it would be frustrating, but actually, it's going really well."
The dancing duo revealed that they will have to cha cha "straight out of the gate," and the ballroom pro says their take on it is "fast, sexy, fun, high energy!"
ET also caught up with the pair on Wednesday at Planet Hollywood in New York City, where DiMarco revealed Murgatroyd has already helped him boost his confidence on the dance floor.
"The first day that we met, right before she came in, of course I've never danced ever. So that's what I was nervous about," he shared. "I didn’t want to look bad on the first day of rehearsals. Now I'm not nervous at all. All thanks to her."
Murgatroyd echoed his statements, praising DiMarco for his hard work and dedication in rehearsals.
"He's doing amazingly well. Part [of that] is just his amazing work ethic," she gushed. "He literally doesn't sit down. Usually people will sit down every five minutes, but he works constantly throughout the four hours that we have."
"He's just so visually aware," she added. "Probably doubly as visually aware as anyone else because he doesn't have hearing. He picks up the steps very quickly, and its very surprising. At first I was really nervous, too. I didn't know how it was going to go. I wanted to be clear, I wanted to make sure that I could be the best teacher possible."
If the pair does win season 22, it will be the second time Murgatroyd has won DWTS. She and NFL star Donald Driver took home the mirror ball trophy during season 14.
DiMarco is joined in the competition by an all-star cast that includes Jodie Sweetin, Mischa Barton, Ginger Zee and Super Bowl 50 MVP, Von Miller.
Miller is paired with pro Witney Carson, who ET also caught up with at the KCAs. The newylwed dished on how the NFL pro was shaping up in the ballroom.
