The women embarked on the long road leading to the mirror ball trophy in part two of the season premiere of "Dancing with the Stars." ET's special correspondent Marie Osmond spoke to all of the dancers backstage after the show.

Singer Macy Gray won over the hearts of the audience--and Marie--with her debut routine and personality. She brought the audience, even her male opponents, to their feet. Lost in the whirlwind of emotions, Macy didn't even realize the response she had earned. She appreciates the commitment of her partner Jonathan Roberts, saying, "The thing about Jonathan is…he loves dancing, so it's really infectious and you kinda get excited about it with him."

One-time rocker chic Kelly Osbourne morphed into an elegant ballroom dancer. She told Marie, "If you would have seen the person that I was a year ago compared to now, I don't even think I was capable of doing anything like this or becoming this. That's what's so great about this show. It allows you to become this person that you've always been frightened to be."

Kelly has grown into just that person. She goes on to explain, "I was named after Grace Kelly. I've watched women like Greta Garbo, Grace Kelly, Audrey Hepburn, wanted to emulate Marilyn Monroe and I've never been girly enough."

The experience was very emotional for Kelly and she is grateful she was able to share it with her "mum" and dad, Sharon and Ozzy Osbourne who were sitting on the edge of the dance floor.

Kathy Ireland, joined by partner Tony Dovolani, said that participating in this competition is "right up there with childbirth. It's so hard." However, it is all worth it for the new skill of dancing that she is acquiring.

She said, "How many people in their life get to learn how to dance from a world champion?" Modeling has taught her to accept rejection, so she is ready to take the harsh criticism that the judges may send her way.

The boys crashed the girl's night on the dance floor and joined them for the post-show interviews. Aaron Carter, with partner Karina Smirnoff, joined their fellow scoreboard toppers Joanna Krupa and Derek Hough as they spoke to Marie. He even expressed adoration for the skills of pro-dancer Derek. Aaron said, "I look up to him. I have a lot of respect for you on the dance floor." But he warned, "I'm coming to get you."

The final installment of the "Dancing with the Stars" season premiere is Wednesday night. The lowest scoring male and lowest scoring female will be eliminated after the judge's scores and viewer's scores are combined. For a complete recap of Tuesday's dances, click here.
