Dancing With the Stars marks a huge milestone this year with season 25. While this season is off to a fantastic start, we can't help but reminisce about which other celebrities have won the competition over the years. There are a few Olympians in the mix, of course, but there is also a boy-band member and a former star from The Bachelor. Not to mention pro dancer Derek Hough, who has taken home the mirror ball trophy six times! Check out the full list of winners here.
