Cast members for Season 18 of the hit reality dance competition, Dancing with the Stars, were officially announced this morning and it's a diverse group of individuals who will hit the ballroom March 17!

This season's celebrities and their professional pairings were introduced on Good Morning America, and include a couple olympians, a game show host and a teen pop star, just to name a few!

And this time around, the show has introduced a surprising new twist! At one point during the season, a "switch-up" will occur. America will be given the power to vote and change the pairings in the middle of competition.

Given the bond these couples make as they continue week to week, this twist is sure to create new challenges for the contestants that we've never seen before!

Below, meet the 12 dancers competing for your vote and the coveted mirror ball trophy!
