Aiza Seguerra revealed that she just got out of the hospital a day before her September 28 concert with Charice.
Dubbed Charice and Aiza: The Power of Two (The Unbreakable Tour), the event was held at the Smart Araneta Coliseum.
During one of her spiels, Aiza candidly shared her thoughts on true love.
Aiza asked the crowd: "Nahanap n'yo na ba ang true love n'yo?"
She then said, "Minsan, dumating na pala, pero hindi mo alam, tapos bumalik.
"Itong kantang ito ay para sa mga tao na nahanap na ang tao na para sa kanila at mabibigay nila ang sarili nila sa tao na yun."
The acoustic singer then gave a heartfelt rendition of the song "Araw Gabi."
After her song, Aiza again talked about love.
"Pag nagmamahal ka nang todo, alam mong ipaglalaban mo yun. And we're not just talking about homosexuals.
"If you love someone, tell him or her about your love.
"Love is such a beautiful thing and it is such an amazing thing.
"Pag masaya ka, you infect people. That's all we need right now, especially now.
"This is a very special song for me. This is for you," declared Aiza.
While Aiza was singing, an emotional woman was shown on the huge LED screen above the stage.
It was Liza Diño, the girlfriend of Aiza Seguerra.
