Gabby Allen: Biography, Medical Condition, Relationships, and More

Just about anyone who scanned Love Island in 2017 remembers Gabby Allen — she was the Liverpool dancer who left the villa coupled up with Marcel Somerville. But the story behind her public-facing confidence, from a childhood scoliosis diagnosis to navigating grief and very public breakups, is a lot more layered than a reality TV edit suggests, and this is a closer look at how she built a career out of resilience, fitness, and determined honesty.

Eight biographical facts that trace Gabby Allen’s public life from her early medical journey to her rapid reality-TV ascent.

What is Gabby Allen’s medical condition?

Gabby Allen was diagnosed with scoliosis — a sideways curvature of the spine — as a child. Channel 4 Press, an official primary source, confirmed she has “publicly discussed having had major spinal surgery for scoliosis as a teenager.” The condition, while treatable, often requires significant intervention when the spinal curve exceeds 40–50 degrees. Allen has described the ordeal as a defining moment of her youth — one that later pushed her toward fitness and dance as both therapy and career.

What surgery has Gabby Allen had?

At age 12, Allen underwent a spinal fusion — a procedure where metal rods and screws are attached to the vertebrae to straighten and stabilise the spine. A June 2026 biography-style profile on Newsmatter.uk (a community blog) states the operation lasted 10 hours. Allen herself has referred to the resulting 18-inch scar in interviews, though that figure has not been confirmed by a medical or primary source. The scoliosis diagnosis, the surgery, and the recovery path are the core of her personal narrative — and they explain why she gravitated toward dance and fitness as a young adult.

What was Gabby Allen’s childhood illness?

The short answer: scoliosis. It is not an illness in the infectious sense but a structural spine condition. Allen was diagnosed in her early childhood years, and by age 12 the curve had progressed enough to require the 10-hour fusion surgery. The experience left her with a lasting connection to body movement. According to Channel 4 Press, she trained as a dancer and later became a fitness instructor — a profession she built in part because of, not in spite of, her medical history.

Are Gabby Allen and Casey still together?

No. Gabby Allen and Casey O’Gorman ended their relationship in May 2025, roughly three months after they won Love Island: All Stars in February 2025. The Tab, citing direct reporting from Casey, confirmed the split was mutual and that the pair remained on friendly terms. Gabby later described a specific conversation that led to the breakup, though she has not shared the full details publicly.

Why did Gabby and Casey split up?

In a January 2026 interview with The Daily Mirror (established UK tabloid), Allen said she was “not seeking a serious relationship at that moment.” She alluded to a key conversation with Casey where they realised their paths had diverged. No third-party accounts of the split exist — the narrative comes entirely from the two participants. As of early 2025, neither has publicly confirmed a new relationship.

What this means: The Allen-O’Gorman relationship timeline — from All Stars win to breakup in under three months — fits a broader pattern in reality-TV pairings. The high-pressure environment, public scrutiny, and post-show career demands often strain partnerships that form in the villa. For fans, the pace of the split was jarring; for industry watchers, it was almost predictable.

Who has Gabby Allen dated?

Gabby Allen’s dating history is public by virtue of her career in reality television. Her two most significant relationships — with Marcel Somerville and Casey O’Gorman — both began on Love Island.

Marcel Somerville (2017)

Allen and Somerville coupled up during Love Island series 3 in 2017, finishing fourth. According to IMDb (user-curated database), the relationship lasted about nine months after the show ended. The pair split in early 2018, citing logistical pressures and diverging life goals. Somerville later moved on to a long-term relationship with someone outside the public eye.

Casey O’Gorman (2023–2025)

Allen and O’Gorman met in 2023, though they did not couple up on Love Island initially. They entered a relationship after mutual appearances on Celebs Go Dating in 2023. In February 2025, they returned to the villa for Love Island: All Stars and won the series, reportedly taking home £50,000 (per The Tab (entertainment publication)). Three months later, they broke up.

Other rumoured relationships

Allen has been linked to a few other men in the tabloid press — notably a brief rumour involving a fellow reality star in 2019 — but none have been confirmed by either party. In a January 2026 interview with The Daily Mirror, she stated she was “single, and not rushing into anything.”

What happened to Gabby Allen’s dad?

Gabby Allen’s father, Mike Allen, died of brain cancer in 2020. Multiple entertainment reports — including from The Daily Mirror (UK national newspaper) — state the tumour was a glioblastoma, an aggressive form of brain cancer. Gabby was 28 years old at the time. In a 2026 YouTube interview (per YouTube (public platform)), she described watching her father die as “devastating” and said she had struggled with grief and mental health in the years since. She has spoken publicly about the importance of mental health support, particularly for young adults navigating parental loss.

The pattern: Allen’s willingness to discuss private grief — her father’s death and her own scoliosis journey — separates her from many reality TV stars who keep personal pain off the public record. This transparency has, paradoxically, strengthened her brand as an “authentic” personality in a genre often criticised for superficiality.
