MANILA - When radio and television host Amy Perez was left inside the iconic "Pinoy Big Brother" house after giving "It's Showtime" viewers a sneak peek of the revamped interior, she anticipated the worst: she would be cut off from the "outside world" and become part of the reality television show as a celebrity house guest.

Perez, on Saturday, entered the "PBB" house with comedian Vice Ganda and Anne Curtis. But after a brief tour of the house, the latter two were asked to return to the "It's Showtime" studio, leaving Perez behind. "Huwag naman ganoon, hindi ako handa," said a visibly worried Perez.

"Huwag kang palabiro, Kuya," she added, speaking to the host of the show named after the Tagalog word for an older brother. "May children's party pa ako bukas. Wala ito sa kontrata ko, Kuya!"

Perez was then told that she committed a violation when she took photos of the different rooms, before being teased with a welcome remark."Hindi nga, Kuya? Seryoso ka talaga sa part na ito? Tumataas na itong boses ko," she said.

Perez was soon called to another room, where she thought she would be officially named as one of the housemates.

"Nung tinawag ako ni Kuya na pumasok daw ako sa confession room akala ko andun na asawa ko at mga anak ko tapos may dalang gamit ko!" she shared on Instagram shortly afterwards. "Hay buti na lang pinalabas ako ni Kuya!"

The actual housemates are expected to enter the "PBB" house Saturday night following their three-week stint in Vietnam.
