Dancing With the Stars 2013 returns with Season 17, Week 6 tonight, Monday, October 21, and though it doesn’t have a specific theme, it doesn’t make it any less exciting.

In addition to all of our favorite pairs wowing us with phenomenal performances, we’ll also be graced by pop royalty when Ariana Grande and Mika perform their new single “Popular” in the ballroom. More exciting yet is a new challenge, the “Switch-Up,” in which all of the couples compete in two side-by-side rounds with no prior knowledge of the dance style or musical accompaniment!

Oh, and last but not least, Lacey Schwimmer returns to the ballroom with brother Benji to choreograph the opening number! No word if they’re in the performance, but it will be exciting to see.

We’ll have all of the videos here in case you miss one or want to re-watch, so keep refreshing during the episode — all of Week 6’s performances will be posted below!
