The couples are dancing the Samba, Salsa or Argentine Tango.
Nine couples are left on the show after the shocking and emotional elimination of "The View" co-host Sherri Shepherd last week.
Gladys Knight, who had the lowest scores last week, will continue this week dancing the Samba.
Melissa Gilbert will take on the Salsa after suffering a mild concussion last week.
William Levy hurt his ankle during rehearsal Sunday. He got an MRI and it appears that he is OK to dance. Levy was rehearsing gently with his partner Monday afternoon.
Maria Menounos will also be dancing injured. She has stress fractures in her feet and cracked ribs.
"It's going to be a lot of fun in the ballroom," said Kym Johnson, dancing partner to Jaleel White. "He's got that great booty there that he can shake, so we will definitely be using that to our advantage."
Mark Ballas, Katherine Jenkins' partner, said they will be dancing a passionate Argentine Tango.
Donald Driver and his partner, Peta Murgatroyd, will be doing an Argentine Tango as well.
Karina Smirnoff said her partner, Gavin DeGraw, will wear something colorful, show some skin and embrace the Caribbean lifestyle.
Roshon Fegan and partner Chelsie Hightower will perform a Salsa routine. They said they never want to be in the bottom two ever again.
"The bottom two is not the place to be, man," Fegan said. "That's not where you want to party."
On elimination night Tuesday, there will be a new twist: the two couples with the lowest scores will have to dance for their lives, with the judges then deciding who is safe to move on to the next round.
The action starts at 8 p.m. Monday on ABC7.
