Dancing With the Stars 2013 heads into Week 3 on September 30, and the contestants will be doing the timewarp. While we knew that it was “Hollywood Night” for Season 17, there’s a new twist — it’s old Hollywood Night, with each pair taking on a different decade and classic movie music.

On September 25, the official DWTS account tweeted: “Join us for Hollywood Night next Mon at 8|7c on #DWTS! Our couples will be dancing to movie music from all decades!”

Sounds like fun to us. The accompanying photo was of Brant Daugherty and Peta Murgatroyd striking a pose in rehearsals (natch), which you can check out above. Since they’re not in costume, we have no idea what their dance will be, but we’re hoping it’s some sort of ‘80s jam. Don’t you forget about me, Brant and Peta!

Later, they tweeted a pic of Bill Engvall and Emma Slater as a cowboy and cowgirl, captioned, "Can you guess the iconic Hollywood character @billengvall will be playing? Don't miss Hollywood Night on #DWTS!" Hmm... sounds like a fun night ahead.

Also, while Corbin Bleu didn’t tell everyone what style he and partner Karina Smirnoff are dancing, he posted an adorable throwback photo of him in 1999 on the set of Galaxy Quest. Will he be dancing to fun ‘90s music? We hope so! Check out both photos below, then hit the comments with your thoughts on the decade music.

Catch the next episode of Dancing With the Stars on Monday, September 30 at 8 p.m. ET on ABC.
