The television program Married At First Sight (MAFS) is facing internal discord and public scrutiny surrounding one of its participants, Brook Crompton. Allegations of undisclosed personal relationships and a subsequent pregnancy have surfaced, creating significant tension among show insiders and viewers.

Recent reports detail a complex personal situation for Brook Crompton, a bride featured in the 2026 season of MAFS. While participating in the program, Crompton has been accused of maintaining contact with a former partner, a situation that reportedly developed alongside her on-screen marriage. The controversy intensified with the recent revelation of her pregnancy, which occurred after the filming period concluded but is believed by some to be connected to events during the show. This has led to claims that Crompton was not fully committed to the experiment, raising questions about her emotional availability and the integrity of her participation.

Timeline of Events and Key Figures
The situation involving Brook Crompton has unfolded across several key periods and involves several individuals:

Pre-Filming Period: Reports indicate that as recently as April, just three months before MAFS production began, Crompton was publicly referring to a former partner, Harry, as her boyfriend. This has been cited as evidence of her continued connection to him.
During Filming: It is alleged that Crompton reconnected with her ex-boyfriend, Harry, while still involved in the MAFS experiment. She has denied these claims, stating any reconnection occurred only after her departure from the show. Her on-screen partner, Chris Nield, has been described as having been "friend-zoned" from the outset, with their relationship failing to progress beyond superficial interactions, according to some sources.
Post-Filming Period: After the conclusion of filming, Crompton's personal life continued to attract attention. Reports emerged of her pregnancy and a subsequent engagement to her ex-boyfriend, Harry. One report indicates Harry proposed on Christmas Day while they were on holiday.
On-Screen and Off-Screen Conduct: Crompton has been noted for her outspoken and "feisty" demeanor during the show, engaging in confrontations with other participants, including Stella and Alissa. Her departure from the program has also been described as sudden, with one insider stating she "just booked the ticket and left."

Jealousy as a Motive: One insider suggested that Chris Nield, Crompton's on-screen partner, might be motivated by jealousy. This perspective attempts to shift blame and question the validity of Nield's potential grievances.
Timing of Relationship Split: A source close to production stated that Crompton ended her relationship with her previous partner three months before MAFS commenced and was not with him during the experiment. This assertion directly contradicts other reports that place her reconnection with her ex during filming.
Justification for Partner Choice: Crompton herself has voiced dissatisfaction with her pairing on the show, believing Chris Nield was ill-suited for the experiment and potentially cast for dramatic effect due to his alleged "fat-shaming comments." She has indicated a desire for a more mature partner who would "adore" her.
Focus on External Factors: Some commentary suggests that Crompton's actions, including her public statements and subsequent pregnancy, should be viewed in light of her experiences after leaving the show, rather than as deliberate deception during it.
