Rumer has it that we know the first star who has signed on for season 20 of Dancing With the Stars! Rumer Willis was photographed during rehearsals at the Millennium Dance Complex in Studio City, Calif. on Saturday, Feb. 21, with dance pro Val Chmerkovskiy. And, indeed, Us Weekly can confirm that The Escort star, 26, will be competing on the ABC smash, which premieres on March 16. 

The oldest daughter of Bruce Willis and Demi Moore wore a cutoff gray top and skintight black shorts with tights. The actress looked fit and focused while practicing her steps. 

Though most of the dance pros have been announced for the upcoming season of the ABC competition series, the celebrity cast has not been revealed.
