Actually it was a surprise prepared by the staff of ASAP Rocks.
During the first number, Piolo performs “I’ll Be There For You” from the tv series F.R.I.E.N.D.S. and half-way through the song, Xyriel Manabat and Zaijan Jaranilla, his son in the fantaserye “Noah” joined him onstage.
The two child stars exited afterwards as the music changed from upbeat to mellow as Piolo is about to perform his second number.
When Piolo was singing his second song–“I Want To Hold Your Hand” by the Beatles–his son Iñigo Pascual showed up on video singing the same song. Piolo, who was surprised and already teary-eyed that moment continued the song as if he was singing duet with his son live on stage.
After the song, Iñigo uttered a short but sweet greeting to his father.
“Happy Birthday Pa I Love You,” he said.

So perhaps Alfie Lorenzo now believes that “Iñigo” is real and not just an “imaginary” son of Piolo as he claimed he is.
