'Dancing With The Stars' Cast Photos Show All The Glitz And Glam

"Dancing With The Stars" Season 18 begins Monday, March 17, with a two-hour premiere, and the stars and their partners have been working hard in preparation for the big day. The moves will be just as big, and the costumes just as sparkly, but there's a huge twist this season.

For the first time in "DWTS" history, ABC has changed the rules and will split up partners throughout the season. Viewers will be able to vote and change the dance partnerships, and all couples will be forced to switch at least once. Below are the first photos of the cast with their original partners, but don't get too attached! Who knows who Winnie Cooper (err, we mean Danica McKellar) will end up with at the end.

"Dancing With The Stars" Season 18 debuts on Monday, March 17 at 8 p.m. EDT on ABC.
