Jolina Magdangal proved her skill in evaluating a person's singing ability.

On Sunday's episode of "I Can See Your Voice," Magdangal was tasked to choose the real singer among six contestants.

In the final round, Magdangal opted to pick Lovely Joy Corpuz, who claimed to be a singer and a flight attendant.

It turned out that Magdangal made the right choice, with Corpuz perfectly hitting the notes of Magdangal's hit song, "Kapag Ako Ay Nagmahal."

The "Magandang Buhay" host picked Corpuz over Harold Estampador, who also has a good singing voice.

After pulling off her duet with Magdangal, it was revealed that Corpuz is suffering from cancer, and that she joined the contest to save up for her treatment.

Based on a Korean show of the same title, "I Can See Your Voice" airs Saturdays after "Maalaala Mo Kaya" and Sundays after "Rated K."
