Mark Labbett: Biography, Illness, Wife Split, Children

Few TV quiz contestants are as instantly recognisable as Mark Labbett. The towering figure known as “The Beast” on ITV’s The Chase has become a staple of British television. But behind the buzzer, Labbett’s life has seen major changes—from a type 2 diabetes diagnosis and dramatic weight loss to the end of his marriage. This article brings together the verified facts on his health, relationships, and career, drawing on the most reliable reports.

Full name: Mark Labbett ·
Occupation: Professional quizzer, TV personality ·
Known as: The Beast on The Chase ·
Children: 1 son

Nine key facts about Mark Labbett — one pattern: most aspects of his life are publicly documented, but financial figures remain contested.

What illness has Mark Labbett got?

Type 2 diabetes diagnosis

• Labbett was diagnosed with type 2 diabetes in 2016, according to Yahoo News UK (UK news outlet).

The diagnosis prompted changes to his diet and exercise routine. Reports indicate that Labbett then embarked on a major weight-loss journey, though the exact methods are disputed.

Conflicting reports on weight loss method

• A May 2024 report quotes Labbett saying he lost weight “the old fashion way – I ate less and went to the gym”, without gastric surgery or weight-loss injections (Mirror (UK tabloid)).

Other unverified online claims suggest he underwent gastric sleeve surgery in 2022, but no reputable source has confirmed this. The contradiction underscores the need for caution when reading celebrity health headlines.

Current health status

Labbett continues to manage his diabetes and maintain a lower weight. In interviews he has credited regular exercise, including walking his dog, for his ongoing fitness (Mirror (UK tabloid)). The “Skinny Beast” moniker used by some UK media in 2024 reflects his visibly changed appearance.

The pattern: Labbett’s own account is the most credible, but the absence of medical records leaves room for doubt.

Why did Mark Labbett split with his wife?

Marriage to Katie Labbett

• Mark Labbett married Katie in 2014 (The Sun (British tabloid)). The couple have a son together, born in 2006.
• Reports describe their relationship as an open marriage (The Sun).

The age gap (Labbett is 23 years older than Katie) and the strain of lockdown were cited as contributing factors to the breakdown.

Announcement of separation

• The couple split in 2020 but only made the separation public in early 2024 (The Sun).
• As of November 2024, they were not officially divorced; Labbett previously said divorce would only happen if either wanted to remarry (The Sun (2020)).

The implication: the split was amicable in principle but prolonged in practice, with both parties moving on in their personal lives long before the public announcement.

How many children has Mark Labbett got?

Son born in 2006

• Mark Labbett has one son, named Lawrence, born in 2006 to his wife Katie (The Sun; also cited by Tuko (Kenyan news site)).

Labbett has spoken about his son in interviews, though he generally keeps his child out of the public eye. No other children are documented.

The catch: older biographies may be incomplete, so always verify with recent sources.

What does Mark Labbett do for a living?

Professional quizzer and TV personality

• Labbett is a professional quizzer and has been a chaser on ITV’s The Chase since 2009 (Yahoo News UK).
• He also appeared on the American version of The Chase in 2014 and on the spin-off Beat The Chasers.

Before his television career, Labbett worked as a teacher. His encyclopaedic knowledge and commanding presence (he stands 6 ft 6 in) made him a natural fit for the role. Like other quiz show personalities, such as Anne Robinson Biography: Age, Net Worth, Relationships, he has built a long-running media career from quizzing.

Other media appearances

He appears regularly on panel shows, charity quizzes, and live events. In 2023 he participated in Beat The Chasers and has made cameos on Saturday Night Takeaway. His net worth, though uncertain, reflects a steady income from TV contracts and appearances.

Did Mark Labbett marry his cousin?

Clarifying the rumor

• According to The Sun, Mark and Katie Labbett are second cousins.

The phrase “married his cousin” is therefore technically accurate but misleading. Second cousins share a great-grandparent, which is a distant relation. The rumour likely spread because Labbett himself joked about it in interviews. The marriage was not between close relatives.

What this means: the sensational headline doesn’t reflect the reality of a distant familial connection.

Timeline of key events

The timeline shows that Labbett’s personal and professional milestones are well-documented, with the most dramatic changes occurring after 2020.

Clarity check: confirmed vs. unclear

Confirmed facts

• He is a chaser on The Chase since 2009 (Yahoo News UK).
• He has type 2 diabetes (Yahoo News UK).
• He lost a significant amount of weight – nearly 10 stone (Mirror).
• He has one son (The Sun).
• He and Katie Labbett separated in 2020, announced 2024 (The Sun).

What’s unclear

• Exact net worth (differing figures from the Express (UK tabloid) and Tuko (Kenyan news site)).
• Whether he had gastric surgery (no reliable source confirms this; he denies it).
• Current romantic relationship status (rumoured but not confirmed).
• Full details of the open marriage arrangement (only partial accounts from tabloids).
• Exact date of birth not confirmed in sourced reports.

What this means: the public record is strong on career and family basics, but financial and private details remain contested.

What Mark Labbett says

“I did it the old fashion way – I ate less and went to the gym.”

The quote cuts through the speculation about weight-loss surgery. Labbett presents his transformation as a straightforward lifestyle change, not a medical procedure.

Summary

Mark Labbett remains one of Britain’s most recognisable quiz show figures, but his private life has become almost as public as his on-screen persona. The verified picture shows a man managing a chronic health condition, navigating a high-profile separation, and raising a son – all while performing as a chaser on a prime-time show. For ITV, he remains a valuable asset; his personal struggles have only added to his relatability. For the audience, the lesson is that celebrity headlines often blur fact and rumour – and that Labbett’s own words are the most reliable source on his weight loss, his marriage, and his priorities. For any fan wanting a straight answer: The Beast is still on the show, still quizzing, and still doing it his own way.
