With all the fast footwork on "Dancing with the Stars," the only thing that won't be moving tonight will be Cher's Botoxed face.
The superstar is not only guest judging for Len Goodman tonight, but is also performing.
I've got some predictions. First, the show will open with her singing her 1998 song "Believe" because… what else would the show do and what else would she sing? Also, I'd expect some wardrobe changes because… it's "Dancing with the Stars" and she's Cher.
Cher is no stranger to the show; she sat in the audience when her former daughter/current son Chaz Bono competed soon after his gender surgery in 2011.
Second prediction: a low-scoring star is definitely getting the boot tonight. It's been a wild season so far, with higher-scoring stars going home in surprise eliminations, like Christina Milian and Nicole Polizzi.
But this week will be different. There are two dances to perform, starting with the couples' individual dances. At the end of the show, there will be a dance-off between the two lower-scoring stars, and the judges will decide who gets eliminated.
One of those couples will likely be comedian Bill Engvall and Emma. He may be scoring low, but his charm has sent better couples home week after week. His luck may run out tonight.
The stars will also be performing to Cher's past hits. Actress Amber Riley and Derek are working on a rumba, which should be easy for them. Amber tweeted, "I'm at dance rehearsal, I can't wait to watch! Yall got me hype lol thanks for the love. My first big performance solo ☺️."
Disney star Corbin Bleu and Karina have the Argentine tango, which should be sharp, considering what these two have shown so far.
Actor Brant Daugherty and Peta are practicing a foxtrot, which will probably look polished, just so long as it's not hollow. Brant tweeted, "Studying the tapes. Always looking for things we can improve #DWTS http://instagram.com/p/gOPVTfsyKD/ ."
Reality star Jack Osbourne and Cheryl are polishing up a tango, which could be decent as long as he nails the character. Jack tweeted, "I'm nervous about tomorrow. :-/ #DWTS ."
Actress Leah Remini and Tony are touching up a Viennese waltz, which will be a change of pace for the actress who has been getting sultry on the dance floor lately.
Bill and Emma have a… disco. Yep, a disco. May as well play up the comedian's silly factor. Bill tweeted, "Great day of rehearsing with @EmmaSlaterDance now off to Wendover,NV for a show. #engvalldwts @DancingABC ."
We will see which star gets the boot Monday night at 8:00 Eastern on ABC.
