Every week is getting trickier in "Dancing with the Stars" Season 21, but the next episode will be a treat to those who love getting into the Halloween spirit. The contestants will be more creative than ever as they stage spooky performances in their bid for the coveted Mirror Ball trophy.

According to a report from Buddy TV, the pairs have finalized their dances for the upcoming week that's sure to be one of the most competitive of the season.

Hayes Grier and Emma Slater will be turning up the romance factor in a waltz set to "Once Upon A Dream" by Lana Del Rey while Alek Skarlatos and Lindsay Arnold will dance the Viennese waltz to "Haunted" by Beyonce. 

Tamar Braxton and Val Chmerkovskiy will foxtrot on the dance floor to "People Are Strange" by The Doors, and Bindi Irwin and Derek Hough will try keeping their winning streak alive with an Argentine tango to "Cry Little Sister" by Gerard McMann.

Three couples will be dancing the paso doble: Alexa PenaVega and Mark Ballas to "Hora Zero" by Rodrigo y Gabriela, Carlos PenaVega and Witney Carson to "O Fortuna" by Carl Orff, and Andy Grammer and Allison Holker to "The Beautiful People" by Marilyn Manson.

Aside from the couple dances, the stars will be split into two teams for competitive group performances. Team captain Carter will be leading Team #Nightmare composed of his partner Burgess, Braxton and Chmerkovskiy, Grammer and Holker as well as Grier and Slater. On the Team #WhoYouGonnaCall is captain Irwin and her partner Hough, Alexa PenaVega and Ballas, Carlos PenaVega and Carson, and Skarlatos and Arnold.

The new episode will be a tough one for the judges and contestants as Deen was booted the previous week leaving a pool of strong contenders who are all jostling for the top spot in the leaderboards.

In her latest exclusive blog from Hollywood Life, Burgess touched on next week's performance saying, "Next week is Halloween week, and Halloween is also Nick's favorite holiday celebration...EVER! I can't say much yet about our plans, but we are super excited about this one!!!"

She added, "There is also a team dance with pros and stars together next week which we're looking forward to. I can't say much about that either just yet, but know it's going to be so epic, I can't wait!!!"

"Dancing with the Stars" season 21 airs on Mondays, 8 p.m., on ABC.
