"Dancing with the Stars" season 20 cast revealed

A new crop of celebrities are ready to put on their dancing shoes for another season of "Dancing with the Stars."

The cast of the competition's 20th season was unveiled Tuesday on ABC's "Good Morning America" -- with the exception of one star, who will be named at a later date.

In a surprise twist, "DWTS" pro Derek Hough -- who was thought to be out for season 20 due to his role in Radio City Music Hall's New York Spring Spectacular -- will be jetting from coast to coast as he's paired with one of this season's celebs.

While we wait on the 12th name, here are the 11 other stars poised to compete for the mirrorball trophy. They include a "Shark Tank" investor, a "Hunger Games" actress, a retired Olympian, a music icon and Michael Sam, the first openly gay player drafted by an NFL team.
