Find out who's dancing with whom and what to expect.

Each of the six couples picked an eliminated pro or troupe member for the trio dance, whose styles will include the paso doble, the samba and the foxtrot.

Robertson is looking forward to strutting her stuff alongside another woman, telling ABC News, "I think I'm going to learn a lot from it. I mean, of course I learn a lot from Mark, but it's different having a girl there doing the same moves as me, and I think that it will challenge me to be better."

Chmerkovskiy joked that Motsepe added more diversity to the group.

In addition to the trio performance, each couple will tackle a dance style voted on by the viewers.

"Dancing with the Stars" begins at 8 p.m. Eastern time on ABC. By the end of the night, one couple will be eliminated, while the other five will advance to the semifinals.
