The full list of celebrity cast members of "Dancing With the Stars" season 20 will not be announced until Tuesday but the rumored roster of names who will join the upcoming installment of the hit reality dance show has been going around online. 

On Sunday, The Daily Mail posted photos of "DWTS" pro dancer Valentin Chmerkovskiy who appears to be rehearsing with Rumer Willis at the Millenium Dance Complex located at the Studio City. In the photo, the 26-year-old actress, known for appearing in several films such as "House Bunny" and "Now and Then," seems to be very focused while following the pro dancer's instructions. She was wearing a skimpy tank top with sheer dark nylons and black hot pants, matched with a pair of dancing heels. 

Aside from movies, Rumer is also known as a part of a very famous Hollywood family. Her father is the blockbuster action star Bruce Willis, while her mom is the critically-acclaimed actress Demi Moore. She also has two sisters Tallulah and Scout, who are starting to make names for themselves. 

Although the rehearsal pictures are already going around online, Rumer, Val, and ABC still have to confirm if the speculations about it are accurate. 

One thing is for sure, Val will join the rest of the 12 pro dancers in the upcoming 20th season of "Dancing With the Stars." His name is one of the first 10 that were announced this season, along with Mark Ballas, Sharna Burgess, Witney Carson, Artem Chigvintsev, Allison Holker, Kym Johnson, Peta Murgatroyd, Emma Slater, and Tony Dovolani. The remaining two will be announced with the rest of the celebrity cast in a special edition of ABC's Good Morning America on Feb. 24.  A live stream of the announcement can be seen here.

Aside from Rumer, other celebrities who are rumored to join the popular reality dance contest include Roseanne Barr, Lalah Hataway, Malcolm Butler, Ross Lynch, as well as Robert F. Kennedy Jr. 

"Dancing With the Stars" season 20 begins on March 16.
