MAFS UK’s Polly Sellman fires back at troll after four-stone weight loss

Polly Sellman, a 30-year-old former MAFS UK contestant who now lives in Australia, has fired back at a cruel troll who body-shamed her after she shed four stone. The ITV/Channel 4 crossover star rose to prominence on Married at First Sight UK last year, and she has since overhauled her lifestyle while building a new chapter Down Under.

In a recent Instagram post, Sellman showcased her figure in a sleek black co-ord and a string of summer selfies from Sydney, illustrating the dramatic transformation she has undergone since moving to Australia over Christmas. The post captured a string of images from a sun-drenched stretch of the Australian coast to casual beachside moments, underscoring her ongoing fitness and wellness journey. Sellman has publicly chronicled her weight-loss progress, noting that she began a six-month effort to slim down earlier in 2024 and shared that she had reached about a four-stone reduction with a goal of maintaining a healthy, balanced lifestyle.

The trolling comment targeted her four-stone weight loss and referenced a controversial diabetes drug. A follower wrote: "Wow maybe if Ozempic had existed when you went on MAFS the guy would have been attracted to you." Sellman did not stay silent, replying in a tone that reflected her blunt online persona: "F**k off Millie [heart emoji]." The exchange quickly circulated among fans and critics of reality TV culture, highlighting how public figures can be subjected to unsolicited judgments about body image.

Sellman’s MAFS UK arc began with her marriage to Nottingham barber Adam Nightingale. The couple’s relationship was a central focus of the show, culminating in a contentious final dinner party that played into their eventual split. In early 2025, she addressed questions about her absence from the explosive MAFS UK reunion, which taped two days after the season’s dramatic finale. She shared a brief TikTok explanation, saying she pulled out two days before filming and was in Centre Parcs at the time, choosing to prioritize her headspace and close friendships over sensational TV moments. This context helped fans understand that her decision was rooted in personal well-being rather than a lack of interest in the show.

Since relocating to Australia, Sellman has opened up about the factors behind her dramatic weight loss. In late 2024 and early 2025, she posted updates describing how she achieved her goals: increasing water intake, eating less, and moving more. She has emphasized that her objective is not rapid, restrictive dieting but sustainable changes that foster a healthier relationship with food and exercise. In a September 2024 post, she wrote that she had begun a six-month mission to slim down and revealed that she had dropped from around 16 stone to approximately 12.5 stone, a shift she described as a turning point in her fitness journey. She has since expressed confidence in her appearance and a new sense of comfort in clothing styles that flatter her frame, highlighting a shift in how she approaches fashion and self-presentation.

The transformation has become a defining element of Sellman’s public narrative since leaving the UK reality TV circuit. She has framed her journey as one of personal growth, rather than a response to external scrutiny, and has continued to document milestones — from workouts to sun-soaked days in her new home country — to inspire fans who follow her updates on social media. Supporters have praised her honesty about the challenges of weight loss and the importance of maintaining a balanced lifestyle amid online scrutiny.

As Sellman continues to navigate life in Australia, her story remains a touchstone in discussions about body image, celebrity culture, and the pressures faced by reality TV participants. Her willingness to openly discuss both the highs of transformation and the realities of online trolling reflects a broader conversation about accountability, resilience, and wellness in the public eye.
