The fourth season of the reality game show Pinoy Big Brother: Celebrity Edition, subtitled Collab, stylized as Celebrity Collab Edition 2.0, aired on GMA Network for 127 days from October 25, 2025 to February 28, 2026.

This season features teen celebrities from the talent agencies Star Magic and Sparkle GMA Artist Center. As part of a collaboration between ABS-CBN Studios, the franchise holder, and GMA Network, the season continues the format akin to the preceding celebrity season, which sees housemates from both networks compete in groups throughout the show's run. The season is presented by a roster of hosts led by Bianca Gonzalez, with Luis Manzano returning as a presenter.

After 127 days, Caprice Cayetano and Lella Ford were named the winners at the finale held at the Crossroad Center.

This was the last season held at the Big Brother house on Eugenio Lopez Drive in Quezon City where it had been located since the inception of the Philippine franchise in 2005.

Format The season is the second run of the Celebrity Collab Edition, which features celebrities signed to the talent agencies Sparkle GMA Artist Center (locally known as Kapuso) and Star Magic (locally known as Kapamilya), with one housemate from each agency being named a winner at the end of the season.

Collab 2.0. format On Day 8 (November 2), Big Brother revealed the "2.0" format. Before the duo phase, the housemates competed as part of various groups with equal members of Kapuso and Kapamilya housemates. Before the nominations, the groups compete against one another for immunity in Ligtask challenges. Afterward, the nominations take place, where each group nominates another group for eviction.

All members of the group with the most nomination points face the public vote conducted through the Philippine e-wallet Maya, with the Kapuso housemate and the Kapamilya housemate with the least votes being evicted from the house. On Day 58 (December 21), the show briefly reverted to the regular Collab format from the previous season, where the housemates compete as duos. However, unlike the previous season, the public votes to save housemates individually, rather than by pair. Like the previous season, the process will repeat until one Kapuso and one Kapamilya housemate are voted to be the Big Winners at the end of the season.

Housemates

On Day 1 (October 25), all 20 celebrity teen housemates entered the house, tying the previous season for the largest cast for a celebrity edition of Pinoy Big Brother. Leading up to the series kickoff, eight of these housemates were revealed from October 21 to 24, 2025, with two housemates introduced daily through 24 Oras. Each revealed housemate was also featured in an exclusive individual interview.

Houseguests Within the framework of Pinoy Big Brother, the term "houseguest" designates an individual invited to enter the Big Brother house. Some of these houseguests are introduced with the explicit purpose of residing for an extended duration and deliberately chosen to influence the dynamics among the official housemates—thereby affecting relationships or altering the competition's trajectory. Conversely, other houseguests serve primarily as visitors; their stay within the house is typically brief, often entailing specific tasks assigned by Big Brother, or their presence fulfills a particular purpose. This can include, for instance, introducing a new game twist, presenting a unique challenge to the housemates, providing gifts to the housemates, or engaging them in conversation.

For this season, the following individuals entered as houseguests:

Notes

The task, which was called as Reverse Class Picture, challenged the housemates to avoid being photographed by Ma'am Castro, who was blindfolded. Being caught meant elimination. The goal was to be the last housemate remaining, who would then be declared the group leader. This process was repeated five times in total, establishing the following leaders: Anton, Krystal, Carmelle, Reich, and Miguel. These five leaders will then choose from the remaining housemates the members of their respective group. Anton went first, followed by Krystal, and so on, leaving Miguel with the "unchosen" housemates. Anton chose Joaquin, Sofia, and Lella; Krystal chose Iñigo, Marco, and Clifford; Carmelle chose Heath, Rave, and Caprice; Reich chose Waynona, Fred, and Princess; and Miguel got Lee, Ashley, and Eliza. Housemates had to grab something from a pabitin corresponding to a straight forward instruction (grab the star-shaped item) or the answer to a Filipino question (sixty-nine minus forty-six and the Tagalog of "notebook"). There were three rounds. For the first two rounds, the six slowest housemates for each were eliminated. For the final round, the three fastest housemates received amulets and became the second set of group leaders. Unlike the first cycle, the leaders chose their members alternately. Housemates had to place sticks on the back of their hand with the palm facing down. Then, they have to flip the sticks and catch them with the same hand's palm still facing downwards. Housemates had to do this once for each of the five stations within three minutes. The four housemates with the most sticks caught (time spent as tiebreaker if necessary) became the third set of group leaders. Like the second cycle, leaders chose their members alternately. Heath and Miguel were automatically paired after winning the first Gift of Immunity challenge. Housemates had to answer the question "In the classic Christmas song Twelve Days of Christmas, how many gifts did the true love send on the twelfth day?" Housemates lined up to answer the question. Those who answered '78' were able to choose their duo while those who answered incorrectly went to the back of the line. The cycle repeated until only two housemates remained in line. Housemates had to listen to the "Story of Miggy" and answer three questions about it. They would do so by flipping each photo card then grabbing and placing the photo card corresponding to the answer on a separate platform. They must shout the answer to get a check. They could only move on once Big Brother said so. Princess, Clifford, and Joaquin chose members alternately, with their first picks being from the other talent agency i.e. Sparkle leader chose a Star Magic housemate first and vice versa. Housemates took turns throwing an object to the top of a house that is sitting on a pole. If a housemate missed, they had to wait for their turn. If not, they chose which group they would want to be part of. Each group had the same number of housemates per agency per gender. The two groups chose Ashley and Joaquin as their group leader. For the final group formation, The Ultimate 8 housemates will form consisting of Big Four of two agencies by series of challenges.

Nomination history Groups or duos who received three points and one point are separated by a semi-colon, as shown in the table. Underlined names denote the intended target for that specific point, if any. Otherwise, no target was identified.
