Big Brother mole twist sparks fan theory that a major star could enter the house

ITV introduced a surprise mole twist just hours before Big Brother's live launch. A group of content creators called the Bov Boys lived in the Big Brother house for a 24-hour trial run on Twitch and YouTube. Producers later told the group that one of them had to stay behind and act as the show's secret plant when the official housemates moved in.

Viewers immediately drew a parallel with Chantelle Houghton's 2006 Celebrity Big Brother stunt, in which an unknown contestant posed as a fake celebrity. Fans suggested this new twist flips that idea: a little-known celebrity or content creator pretending to be an ordinary participant. Some fans even speculated Chantelle could appear as part of the task, though reactions were mixed and not everyone agreed the comparison works.

The Bov Boys weren't the only content creators involved. Guests who took part in the trial included Adeola Patronne, Mariam Musa, Pieface, Scouse Mali and Shauna Games. The identity of the mole was confirmed would be revealed during the live launch show, presented by AJ Odudu and Will Best at 9pm on ITV2 and ITVX.

Fans on social channels picked up on the clue and shared theories. One common observation: the twist resembles a reversed version of the 2006 task. Another counterpoint raised by viewers: minor celebrities already often resemble civilians, so the concept may not be as dramatic when flipped.

Expect the live launch to show the mole reveal and how the real housemates react to a planted outsider. The production's framing of the task as a major job suggests producers want the mole to actively influence early dynamics.

The mole twist is part of Big Brother's opening-night strategy to introduce immediate tension. The live launch will reveal the mole's identity and set up the first phase of the game. After that, standard Big Brother processes—nominations and public votes—will resume, with the mole's actions likely shaping early alliances and conflicts.
