Pinoy Big Brother: Celebrity Edition 2

Pinoy Big Brother: Celebrity Edition 2 was the second celebrity edition and the fifth series overall of the Pinoy Big Brotherfranchise. It started on October 14, 2007, and ended twelve weeks later on January 5, 2008, at the Araneta Coliseum. It was supposed to end on December 22, 2007, but it was announced on November 19, 2007, to be extended for two more weeks.

Toni Gonzaga reprised her role as the primetime host, while ex-Update host Bianca Gonzalez helmed a brand new show, Pinoy Big Brother Über. UpLate host Mariel Rodriguez also hosted Über for seven days with Bianca; but for rest of the program's duration, she was also the House's first and longest-staying houseguest. This new season also marked the hosting debut of second season winner, Beatriz Saw as she hosted the Updates.

The theme song, Sikat ang Pinoy originally sung by host Toni Gonzaga and PBB 1 alum Sam Milby, was rehashed and was performed by Pinoy Dream Academy Grand Star Dreamer Yeng Constantino and PDA finalist Eman Abatayo.
