‘Dancing with the Stars’ Season 27: Here are the Trio Week dances, which will feature some old and new faces

It takes three to tango on “Dancing with the Stars” — and to cha-cha, paso doble, salsa, Argentine tango and Charleston. Week 4 is Trio Week, but with a twist this time. While pros and troupe members have joined couples in the past, the show is bringing in former contestants, “Dancing with the Stars: Juniors” contestant Maddie Ziegler (as previously announced), and two people who have absolutely nothing to do with the show whatsoever.

Scarlett Byrne, who played Pansy Parkinson in the “Harry Potter” films, will team with her former co-star Evanna Lynch and Keo Motsepe for their salsa, while “Bachelor in Paradise” star Jordan Kimball will hit the hardwood with Grocery Store Joe and Jenna Johnson for their salsa. Stay thirsty, ABC.

Former champs Melissa Rycroft and Rashad Jennings, and alums Nastia Liukin, Linsdsey Stirling, Riker Lynch, Joey Fatone and Amy Purdy are the past contestants who’ll take another step on the dance floor. Purdy is dancing with Tinashe and Brandon Armstrong, and you have to wonder if the show had planned to match her with her fellow Paralympian Danielle Umstead, who was eliminated in Week 2.

One couple will be eliminated at the end of Mondays’ show.
