With tonight's (11-24) grand finale results show on "Dancing With the Stars," judge Carrie Ann Inaba says she's always a fan of the people with the biggest transformations.

"My favorite type of competitor is the people who never had an ounce of dance training. I just find watching their whole transformation process exhilarating. Seeing them get it still gets me excited after all these years. It's what I love and it's nice to see other people tap into it and find an attachment to it."

Of course, Kelly Osbourne is this season's most transformed competitor, particularly among her fellow two finalists, Donny Osmond and singer Mya.

Dance backgrounds or not, Inaba tells us that the celebrities come into the competition very prepared for how intense the experience is going to be.

"The competitors themselves come with a lot more knowledge as far as what they're getting into. I don't know if our expectations go up each season, but I think their own expectations go up because they know more about the show. We find that people come to the show and they have these expectations of how far they're going to go. Some of them are realistic and others not so much," she says.

Inaba, who's taken some flack for being tough on the competitors, admits, "It's never easy to look somebody in the eye who's giving it their best and give them what may seem like bad news, especially if they didn't do as well as they hoped to do. It's human nature to have a difficult time with that, but when you put it in perspective, often a lot of people will grow from constructive criticism," says Inaba.

"From my experience, you have to be honest. I know it works and I know it helps people to grow. If you keep saying, 'Oh, that was great. You're wonderful,' then they'll never get better. They look for us to be the experts. If they listen to what we're saying, often they will improve."
