Kirstin Maldonado is feudin’ for a cause…

The 29-year-old half-Mexican, part-Spanish American singer and her Pentatonix group mates are facing off against Wilson Phillips on Sunday night’s new episode of Celebrity Family Feud.

In a clip from the upcoming episode of the primetime ABC game show, premiering exclusively on Billboard, host Steve Harvey introduces the Grammy-winning a cappella group.

“Y’all can sing,” Harvey tells the quintet.

Harvey introduces each individual member — Scott Hoying, Maldonado, Matt Sallee, Mitch Grassi and Kevin Olusola — and pays special attention to the “smooth” pronunciation of beatboxer Olusola’s last name.

Pentatonix recently released a deluxe edition of their latest album The Lucky Ones on September 10, via RCA Records, following up the album’s initial February 12 release with seven additional songs.

One of those new tracks is “Midnight in Tokyo,” for which PTX joined forces with all-female Japanese vocal group Little Glee Monster and released a music video along with the deluxe edition.

Tune in to Celebrity Family Feud at 8:00 pm ET on Sunday night on ABC to see Pentatonix take on Wilson Phillips for harmonic supremacy.
