After a shocking and scare-tastic Halloween week that sent Hayes Grier home and gave Derek Hough his first ever team loss in 13 years, seven couples head to week 8 of "Dancing with the Stars" season 21, where they will honor the important people in their lives.

The pairs will dance their heart out for the most significant people in their lives this week and they have to do so excellently because the pair with the highest score will not only get to make their loved ones happy but will also receive immunity.

The contestants are only three weeks away from the "Dancing with the Stars" season 21 finale and the immunity sure helps in catapulting the best dancing couple there. Plus, the highest-scoring pair will also secure extra three points for next week.

The winning pair will then automatically head to week 9 but the remaining six couples will have to do some dance-offs in order to earn extra two points and a spot for next week. However, apart from the three judges, the contestants will have to as well dazzle the public, who gets to vote this week too.

In "Dancing with the Stars" season 21 week 8, viewers can expect the couples to perform some Argentine Tango, Contemporary, Foxtrot, Salsa, Paso Doble and Viennese Waltz. Here is the complete rundown of the couples and the respective songs they will dance to:

  • Alek Skarlatos and Lindsay Arnold: "Holding Out for a Hero" by Ella Mae Bowen
  • Alexa PenaVega and Mark Ballas: "Viva La Vida" by Coldplay
  • Andy Grammer and Allison Holker: "Isn't She Lovely" by Stevie Wonder
  • Bindi Irwin and Derek Hough: "Grace Kelly" by MIKA
  • Carlos PenaVega and Witney Carson: "Valio La Pena" by Marc Anthony
  • Nick Carter and Sharna Burgess: "Can't Help Falling in Love" by Haley Reinhart
  • Tamar Braxton and Val Chmerkovskiy: "Born This Way" by Lady Gaga

"Dancing with the Stars" season 21 week 8 airs Nov. 2 at 8 p.m. ET on ABC.
