Brooke Burke and Derek Hough waltzed their way to a stunning championship victory Tuesday night on the "DWTS" finale -- and they were nothing less than perfect, again!

"Unbelievable!" Brooke exclaimed as she and Derek were awarded the coveted mirror ball trophy. "I can't believe it," Derek agreed. The two were then promptly hoisted atop the shoulders of their all-star castmates.

Reprising their Viennese Waltz, the new champs scored a perfect 30 from the judges for the second night in a row, moving Bruno Tonioli to roar, "You truly are the jewel of the crown of this really grand finale!"

Despite their perfection, Brooke and Derek faced hot competition from their fellow finalists right up to the end. Warren Sapp and Kym Johnson scored a 27 dancing the hustle, and Lance Bass and Lacey Schwimmer notched a 28 with their jitterbug.

When all was said and done, former NFL star Warren declared his "Dancing" experience "absolutely wonderful." And Lance said his successful stint "has so been worth it. This has been the most fun I've had in my entire life."

The finale was, as expected, a star-studded affair, with all this season's contestants taking a final spin on the dance floor. One of many highlights included Kim Kardashian and pro partner Mark Ballas grooving to Sir Mix-A-Lot's rap classic, "Baby Got Back."

Miley Cyrus and Alicia Keys topped off the banner night with rockin' live musical performances.
