'Dancing With the Stars' to Premiere: What to Expect From the New Season

There are new faces in the ballroom and on the judges' panel.

Hough -- whose brother, Derek, will be back as one of the pros -- doesn't plan on holding back her opinions.

"I judge the way that I teach. And, you know, if you saw previous seasons that I was on, I was not afraid to crack the whip on my dance partners," she told ABC News. "I do have my little halo, [but] it's held up by my devil horns."

In another wrinkle to the format, there will be a separate results show during at least the first two weeks of competition. Last season, "Dancing with the Stars" aired only once per week throughout the competition.

If Sabato wants to finish in first place, he'll have to battle through the pain he's already been experiencing in rehearsals. He says he's been taking a lot of Advil, adding, "The hips are hurting. Everything is new. The mind is working really fast to get all these moves."

However, he noted, "I’m just blessed to be a part of this."

Thompson said she is simply hoping to have fun on the dance floor, despite some concerns she has about doing the show.

"That's really great about dance, because once you just let it go, it's just joy, and I'm hoping to get to that spot again," she said.

On the first night of "Dancing with the Stars," which begins at 8 p.m. ET, each couple will dance either the cha cha, the foxtrot or the jive. One couple will be eliminated the following night on the results show, which will air at 8 p.m. ET and will feature musical guests Smokey Robinson and Aloe Blacc.

Here's a rundown of this season's couples:

* Tommy Chong, one-half of the comedy duo Cheech and Chong, and Peta Murgatroyd
