With the support of her mother in the audience, Mya and partner Dmitry Chaplin were awarded one of the highest honors on "Dancing with the Stars," the first perfect 30 of the season. ET's special correspondent Marie Osmond spoke with the scoreboard toppers, as well as the four other remaining couples.

The Grammy-winner felt like she was living in a dream telling ET, "When you're in rehearsals, yes, you think about a 30, but more importantly, you think about giving a great performance and when a judge named Len [Goodman] comes around and gives you a 10 for the first time, I was going to faint."

Calling partner Joanna Krupa "Super Krupa" for her futuristic comic book character inspired outfit, Derek Hough praised her commitment, saying, "A sign of a true champ is somebody that goes through a struggle, doesn't do quite well, but then can pick themselves back up, sink or swim, and she swam, [and] did a great job in the Paso and really proved that she deserves to be here."

Donny Osmond and partner Kym Johnson really got into their '80s theme, going all out in their costuming. Donny joked, "It's a wig, it's a hat, and an animal, all rolled up in one." To further get into the era, '80s musical acts Taylor Dayne and Jody Watley joined Marie as her guests for the evening.

Reality star Kelly Osbourne also enjoyed getting into character. She admitted, "Next to the dancing, it's my favorite part of the entire show, getting to make these dresses."

Five couples will become four on Tuesday night's results show of "Dancing with the Stars" on ABC.
