It’s Cher week on Dancing With the Stars Season 17. The final seven couples each have two dances on Week 8 — an individual routine and the Dance Off challenge — and they’ll be judged by Cher, who is both filling in for Len Goodman and performing two songs. Not only that, every couple will be dancing to Cher songs. So it’ll be a true Cher-a-palooza! Here’s what we know so far about the Monday, November 4 dances.
