The Finals Night was divided into two rounds.
In the first round, the three finalists sang with their favorite duet partners from their previous performances. Chairman Fernando chose Asia's Queen of Songs Pilita Corrales, and they sang the Filipino folk song "Ay, Ay, Ay, O Pag-ibig." Joey did a rendition of Kenny Rankin's "What Matters Most" with friend and Kung Ako Ikaw co-host Keempee de Leon. And lastly, JC took the stage once again with Allan K where they sang The Foundation's "Build Me Up Buttercup."
