The "Dancing With the Stars" cast won't be announced until Tuesday, Feb. 24, but a leaked photo hints that Rumer Willis will be competing for the coveted Mirror Ball trophy for Season 20. The pictures were published by the Daily Mail and show Willis - the daughter of Bruce Willis and Demi Moore - practicing her dance moves with Val Chmerkovskiy at the Millennium Dance Complex in Studio City.

It's been rumored for a few months now that the 26-year-old was joining the cast. Other celebrity names tossed around include Roseanne Barr, New England Patriots Malcolm Butler, Lalah Hathaway, "The Bachelor" star Chris Soules, reality TV star Savannah Chrisley, radio host Robert F. Kennedy Jr., "Shake It Up" actress Bella Thorne, Jack Nicholson and Disney Channel star Ross Lynch.

The confirmed professional dancers are: Mark Ballas, Chmerkovskiy, Peta Murgatroyd, Tony Dovolani, Kym Johnson, Sharna Burgess, Emma Slater, Artem Chigvinstev, Allison Holker and Season 19 winner Witney Carson.

Cheryl Burke and Derek Hough previously announced that they wouldn't be a part of Season 20. Hough is sitting out the season because he's performing in Radio City Music Hall's "New York Spring Spectacular" and Burke is doing a reality show for NBC.

Newly engaged Karina Smirnoff also announced her exit from the dancing competition show revealing on Instagram that she wanted to focus on other things like her new book "We're Just Not That Into You - Dating Disasters From the Trenches."

"I've decided to focus my energies on some other exciting endeavors including adding author to my resume," she said. "I have absolutely loved dancing for all of you for all these years and feel blessed to have been given a platform to put my passion for dance, choreography and creativity on display. DWTS has been a huge part of my life for the last 10 years and I will always have a special place in my heart for it."

Season 20 of "Dancing With the Stars" premieres March 16 on ABC.
