MANILA - Bea Alonzo entered the "Pinoy Big Brother" house on a mission in the reality show's episode that aired Tuesday, getting thrilled reactions from the unsuspecting housemates.

The "Sana Bukas Pa Ang Kahapon" star, along with leading man Paulo Avelino, were tapped by Big Brother as accomplices in distracting the housemates from their weekly task -- to stay perfectly still at specified moments, with only three chances for error throughout the week.

Separately, Alonzo and Avelino visited the living room during a halt for the weekly task.

Both approached the visibly surprised housemates and attempted to make them laugh.

The housemates, however, managed to stay in their positions.

Only when their visitors returned to the confession room did the housemates express their shock, belatedly shouting and cheering over the fleeting interaction with the prized ABS-CBN stars.

In a preview for an upcoming episode of "Pinoy Big Brother," Alonzo is seen returning to the living room, this time to give advice to celebrity housemate Jane Oineza about her problems inside the house.

"Pinoy Big Brother: All In" airs weeknights on Primetime Bida, and on Saturdays and Sundays as part of ABS-CBN's Yes! Weekend line-up. Afternoon updates are also aired via "Uber" on weekdays.
