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.

Amber Riley and Derek Hough, Rumba

Amber and Derek have Rumba this week, and Derek told On the Red Carpet he's going to have to break out his "love hand." Amber's reaction? "Awwwkwaaaard." She echoed that in her Parade blog: "It’s going to be really interesting because you have to be so sexy and intimate… and Derek’s like my brother. So it should be an interesting week!"

In her blog, Amber also shared some details about the Dance Off. “If you get the highest score of the night, you don’t have to participate in the dance-off challenge. If you get the second-highest score, you get to choose who you want to challenge in a dance. Obviously, we’re going to try to get the best one of the night because I don’t want to be pitted against anybody! I don’t want to have to choose anyone, and I don’t want to be placed against any of my fellow castmates. It’s still a competition so you have to be strategic and smart."

When it comes to Cher as guest judge, Derek told OTRC he hopes she sings the scores. It’s kind of surprising that Bruno hasn’t been doing that this whole time.

Bill Engvall and Emma Slater, Disco

Bill tried to quit so Snooki could stay, but now that he's here, he hopes he can take Emma to the Finals. He figures people are voting for him because he's just a regular guy without celebrity friends. He represents the people.

Watch their On the Red Carpet interview to hear them try to explain the Dance Off, and talk about how much they love Cher. Last year Bill went to a party as Cher. Emma said she's going to try and dig up that photo of him. They don't discuss their dance style, but Bill tweeted, "First day of rehearsals this week. Dancing disco and CHER is going to be there. Suhweeeet. #engvalldwts @EmmaSlaterDance @DancingABC."

So they have Disco and a photo of Bill dressed as Cher. He's golden.

Leah Remini and Tony Dovolani, Viennese Waltz?

After Monday's show, Tony wasn't sure about their individual dance. He thought it might be Viennese Waltz, but he wasn’t positive. Tony told OTRC Cher might even know know Viennese Waltz, since she comes from an era where ballroom dance was very popular. He thinks she’ll bring as much to the table as the other judges. Leah quipped, "There's a lot of people who judge a lot of things that have no right judging." Tony added, "Like all the bloggers." Blogger feud!

Jack Osbourne and Cheryl Burke, Tango

"Next week is Cher week and we've got the Tango," Cheryl told OTRC.

In other news, Cheryl wants the half-point scores back, since everyone's scores are so close. She also thinks Bill could go all the way, since this is his demographic. Jack also thinks Bill has shown great improvement — he’s leaps and bounds from where he was seven weeks ago.

And, for whatever reason, they also talk about Jack's gas problems.

Elizabeth Berkley and Val Chmerkovskiy, Jazz

Isn’t Elizabeth a jazz dancer? Just this past week, in her critique of their Quickstep, Carrie Ann Inaba said Elizabeth wasn’t doing the individual stuff jazz dancers normally do. So maybe this week will be especially good for Elizabeth. She and Val told OTRC it’s their mission to impress Cher — they want to be her favorite couple.

Corbin Bleu and Karina Smirnoff, Argentine Tango

"Next week all the songs are going to be Cher songs," Karina told On the Red Carpet, "so we're going to do the Argentine Tango to one of her songs."

Karina said some of her DWTS costumes have been inspired by Cher. Corbin is also excited for her to guest-judge, and they don't care that she's not a ballroom expert. She judges performance.

Brant Daugherty and Peta Murgatroyd, Foxtrot

After Monday's show, Peta told OTRC they would have either Disco, Viennese Waltz,or Foxtrot. They were still clearing some music for her.

Brant said he was going back to work on Pretty Little Liars the next morning, so whenever he ended up seeing Peta, he'd figure out what they were dancing. Apparently they made time to goof around on the PLL set before doing any dancing, since Peta shared this photo on Wednesday!

UPDATE: Peta updated with a shirtless photo of Brant and this note: "The producers didn't know where to clip the microphone, so @brantdaugherty took it upon himself to find the best possible solution... #noshirtday #lifeisgood haha #foxtrot @dancingabc." No Shirt Day! The Foxtrot isn't really a not-shirt dance, so it was probably just for that day. Alas...
