Jennylyn Mercado, Dennis Trillo perform at LRT-1 station in disguise

Jennylyn Mercado and Dennis Trillo gave commuters a treat by giving them a free concert.

The catch? They had no clue about their real identities.

The Kapuso power couple had donned disguises and did a street performance at an LRT-1 station.

In their latest vlog, the pair showed how that tacked this challenge from start to finish.

Jennylyn and Dennis serenaded confused commuters with OPM classics — including her old single, "Kahit Sandali"!

Before long, they drew a crowd and even received tips.

The station exploded in cheers when they took off their disguises and treated them to one last performance.

The two celebrities also took the chance to raise awareness about the PWD performers that are usually stationed in the spot they performed at.
