Mind-blowingly, it was the 16th season! That doesn't seem possible!
So how did it happen? Kellie and Derek earned perfect 30s for their routines, which even had a dramatic freestyle number that had people in tears! No joke! Then they earned extra points from their cha-cha relay, and squeaked out the win!
We're so proud of the duo, and you gotta watch the winning moment… with clips of their stylish moves (above)!! What a night for them! Is there any reality talent show she can't do well on (we're lookin' at you, American Idol!)??
Oh, and we totally had an EXCLUSIVE interview with Kelly — you should check that out AFTER THE JUMP!
