'Dancing With the Stars' Finale: And the Winner Is…

·Writer

SPOILER ALERT: This recap reveals the winner of "Dancing With the Stars" Season 17.

We have a winner! On Tuesday's "Dancing With the Stars" finale, there was a double shot of dance as the final three couples — Corbin Bleu and Karina Smirnoff, Amber Riley and Derek Hough, and Jack Osbourne and Cheryl Burke — meshed two dance styles together to create a trio of unique routines for their final performances of the season.

After Monday night's perfect-scoring freestyle dances, the last couples standing took on the "24 Hour Fusion Challenge" for finale night, fusing wacky combos like the Cha Cha-Foxtrot and the Samba-Quickstep, before this season's winner was announced. Riley and Hough scored a perfect 30 for their fusion dance, while the other two couples scored 27 points each.

So, after all of that fusion confusion, who's the proud owner of that blinged-out mirrorball trophy?That would be Riley and her pro partner Hough. (Yep, you counted right — that's five mirrorball wins for Hough.)

After her win was announced, an ecstatic Riley said, "I did this competition because I didn't know if I could do it, and anything that scares me I want to do. So I want to let women of all sizes out there know, you can do whatever you put your mind to. It doesn't matter what size you are, what color you are, you can do whatever, whatever, whatever you put your mind to!"

The whole "DWTS" Season 17 gang was back for finale night. A rebuilt Bill Nye flipped out for a "Weird Science" cha cha (OK, there may have been a body double), and a heartwarming highlight of the show featured the return of fan favorite Valerie Harper to the dance floor. Harper reunited with partner Tristan MacManus to dance to the song "What a Wonderful World" while Colbie Caillat crooned in the background.

Lady Antebellum was also in the house to perform their new single "Compass," and Enrique Iglesias sang his current hit song "Heart Attack." There was even a live performance of Ylvis's "The Fox."

As for the runner-ups, Bleu said that he accomplished what he set out to do this season (and gained a new BFF in Smirnoff in the process), while third place finisher Osbourne dished on what he took away from the "DWTS" experience.

"I've learned I'm definitely not a better dancer than my sister. We are now tied," he joked. (Kelly Osbourne landed in third place on Season 9 of the show.) But Osbourne also added, "I've learned that if you just dive in and you have a great teacher, it is possible to become a ballroom dancer."
