For the first time in the “Pinoy Big Brother” history, constellations of stars from two of the country’s biggest talent pools—ABS-CBN’s Star Magic and GMA’s Sparkle—have come together for the historic "Pinoy Big Brother Celebrity Collab Edition," which officially kicked off on Sunday, March 9. As the doors of Bahay Ni Kuya reopened, the connections between the Kapamilya and Kapuso housemates were put to the test right away, and unexpected twists left both the participants and hosts completely 'shookt.'  

Hosts Bianca Gonzalez, Gabbi Garcia, Robi Domingo, Melai Cantiveros, Alexa Ilacad and Mavy Legaspi officially opened the latest installment. 

To their surprise, Melai , Gabbi, Alexa, and Mavy (Ashley's real-life boyfriend) were instructed by Kuya to welcome the housemates. But in a shocking twist, the four were handed a letter from Kuya, announcing that they too would be staying inside the house—for an indefinite period—to assist the housemates in their first official task. 

Viewers can watch "Pinoy Big Brother Celebrity Collab Edition" online via live streams on Pinoy Big Brother's YouTube page, Kapamilya Online Live (KOL), iWantTFC and TFC.
