Erin Andrews and Tom Bergeron are back with the four judges, Carrie Ann Inaba, Len Goodman, Julianne Hough and Bruno Tonioli, for season 20 of Dancing With The Stars. Tonight each contestant will either do the Cha Cha, Jive or Foxtrot. The couple with the lowest judges scores and viewer votes will be eliminated.

Willow Shields and Mark - Cha Cha. 25. Best known as Primrose Everdeen in the Hunger Games, Willow is the youngest competitor in the shows history.

Robert Herjavec and Kym - Cha Cha. 28. Best known for his role on Shark Tank and dances like the funnest dad.

Riker Lynch and Allison - Jive. 31. Best known as the guitarist in the family band R5. Great rhythm but a bit rough around the edges.

Charlotte Mckinney and Keo - Jive. 22. Best known for her burger commercial on the superbowl. An average dancer but obviously nervous.

Patti LaBelle and Artem - Foxtrot. 25. Best known as a grammy winning singer and performer. Very poised and joyful dancer and very grateful to be on the dance floor. Can you believe she's 70??

Chris Soules and Witney - Jive. 26. Best known as the most recent Bachelor (Prince Farming). Witney was also last season's mirror ball winner. It's hard to tell if he's uncomfortable or too comfortable with the physical touching.

Michael Sam and Peta - Cha Cha. 26. Best known as the first openly gay athlete in the NFL. Because he's a free agent Michael spends his time preparing for upcoming combines. He trains in the gym for 3 hours then dances for 4 hours. His score may not reflect it but he's one to beat.

Nastia Liukin and Derek - Foxtrot. 30. Best known for her 5 olympic medals but Derek is also a 5 mirror ball trophy winner. She's very graceful and obviously a frontrunner.

Redfoo and Emma - Cha Cha. 22. Best known as 1/2 of the pop duo LMFAO. Very fun on the dance floor but the judges find him too kitschy.

Noah Galloway and Sharna - Cha Cha. 26. Best known as an Army combat veteran hit by a roadside bomb. He lost left arm and leg but he doesn't want his missing limbs to be noticeable. The only challenge is judging technique.

Suzanne Somers and Tony - Cha Cha. 25. Best known as an actress and Thigh Master saleswoman. Wearing her best aerobics leotard, she doesn't completely suck.

Rumor Willis and Val - Foxtrot. 32. Highest score of the night! Best known as an actress and daughter of Demi Moore and Bruce Willis. Very passionate and good partner connection. Frontrunner for sure. Bruce could look a little more thrilled after her performance, though.
