Gretchen Malalad

 was a housemate on Pinoy Big Brother: Celebrity Edition 1.

On Day 17, Gretchen left the house after Big Brother allowed her to report to her superiors in the Philippine Air Force (where she serves as a first-class airwoman) to face a summary investigation about her being AWOL.

Big Brother did this with the proviso that she will be blindfolded during the trip and that she cannot speak to anyone except those who were investigating her. She must also be returned to the house 24 hours after she left. She returned 14 hours later after the Philippine Air Force officially authorized her to continue her stint in the show. Then she was later evicted on Day 39.
