How many children has Declan Donnelly got?
Declan Donnelly and his wife Ali Astall have two children. Their daughter, Isla Elizabeth Anne Donnelly, was born in September 2018 (WalesOnline). Their son, Jack Anthony Alphonsus, was born in July 2023. The middle name “Anthony” is widely reported to be a tribute to his professional partner Ant McPartlin.
Donnelly has spoken about becoming a father later in life, framing it as a grounding experience that brought a new perspective to his fast-paced television career.
The implication: fatherhood arrived at a moment of professional and personal stability, contrasting sharply with the chaotic tabloid cycles that often surround the Ant & Dec brand.
What age is Declan Donnelly’s daughter?
Declan Donnelly’s daughter Isla was born in September 2018, making her 7 years old as of 2025 (WalesOnline).
What health condition does Declan Donnelly have?
Public records do not establish a verified chronic health condition for Declan Donnelly. The most widely reported medical event occurred in 2017, when he underwent a “serious” kidney stone procedure that forced him to miss a day of filming for Britain’s Got Talent (KISS / Hello Rayo). He also had his appendix removed in 2014.
Media speculation sometimes conflates Donnelly’s health with that of his partner McPartlin, who entered rehabilitation in 2017 for addiction-related problems (KISS / Hello Rayo). The verified record indicates distinct and separate medical histories.
The public often conflates the Donnelly and McPartlin health narratives. The verified record shows distinct crises — Dec’s isolated kidney procedure and Ant’s well-documented addiction struggles. Treating them as separate stories is critical for accuracy.
What this means: the Donnelly health narrative is one of acute, isolated incidents, not a chronic condition — a distinction his representatives have maintained rigorously.
Who is richer, Ant or Dec?
What is Declan Donnelly’s net worth?
Both presenters are extremely wealthy. Their combined net worth from joint television ventures is estimated at £62 million (Capital FM). Most financial profiles suggest they earn roughly equally from their partnership-driven projects like I’m a Celebrity…Get Me Out of Here! and Britain’s Got Talent.
Individual variations likely exist through personal property investments and side projects, but no independently verified breakdown of their personal fortunes is publicly available.
The catch: without independently audited financial disclosures, any “richer” claim remains a media construct, but the partnership’s equal branding suggests a mutual financial symmetry.
Who was Declan Donnelly’s first wife?
Declan Donnelly has only been married once. He married Ali Astall in 2015 at St Michael’s Roman Catholic Church in Elswick, Newcastle upon Tyne (WalesOnline). There is no legal record of a previous marriage.
The persistent online search for a “first wife” likely stems from his long-term relationship with Clare Buckfield, which was his most significant partnership prior to Astall but was not a marriage (Capital FM).
Why this matters: the viral search query reveals a curiosity about a romantic past that, evidence suggests, never legally existed.
Why did Clare Buckfield and Declan Donnelly split up?
Declan Donnelly’s long-term relationship with Clare Buckfield ran from 2003 to 2014. Buckfield is a television presenter and actress, best known for her role on Gladiators. The split was reported as amicable, with neither party publicly disclosing a specific cause (WalesOnline).
Both have since moved on definitively. Donnelly married Ali Astall the following year, and Buckfield later married actor Neil Newbon. The relationship remains a footnote in his personal history, notable mostly for the privacy both maintained during and after the breakup.
The pattern: neither party has weaponized the split, a rarity in celebrity circles that speaks to a mutual respect absent from many high-profile breakups.
Are Ant and Dec good friends?
Ant McPartlin and Declan Donnelly have been friends since the early 1990s. They met while working on the children’s drama Byker Grove, where they played characters PJ and Duncan (The Daily Mirror). They went on to form a pop duo and eventually transitioned into television presenting, hosting shows like SMTV Live, I’m a Celebrity…Get Me Out of Here!, and Britain’s Got Talent.
They have frequently described their relationship as brotherly. The friendship faced its most severe test in 2018, when McPartlin pleaded guilty to drink-driving following a car collision. Donnelly supported his partner through the public fallout, maintaining the show schedule alone where necessary and keeping any personal strain private (KISS / Hello Rayo).
Do Ant and Dec live near each other?
Whether Donnelly and McPartlin live in the same neighborhood is a matter of media speculation rather than confirmed fact (Media Clicks).
The trade-off: an intensely close personal bond that survived a public crisis which could have ended any professional relationship, revealing a loyalty beyond the camera.
What age is Declan Donnelly’s wife?
Ali Astall was born on May 30, 1978, making her 47 years old as of 2025 — placing her four years older than Donnelly (WalesOnline). She initially worked as a makeup artist and publicist for the Ant & Dec brand before becoming Donnelly’s manager and later his wife.
The couple maintains a deliberately low profile, rarely appearing together at red-carpet events. This discretion is a known preference for Donnelly, who has consistently drawn a clear line between his performing life and his home life.
The implication: the small age gap is incidental; the real story is their professional-turned-personal trajectory, a modern love story in the entertainment industry.
Nine specifications, one theme: a career built on partnership, measured in millions, grounded in family.

This division between public and private defines his career.
What’s clear and what remains speculation
The confirmed facts about Declan Donnelly are straightforward: he married Ali Astall in 2015, he has two children, he was hospitalized in 2017 for a kidney stone procedure, he is 50 years old as of 2025, and he has never been legally married before. These details are consistently reported across major outlets like Capital FM and WalesOnline.
Several areas remain unclear. The exact net worth split between Ant and Dec is not publicly available. No official reason has been given for the split with Clare Buckfield. Whether Donnelly and McPartlin live in the same neighborhood is a matter of media speculation rather than confirmed fact (Media Clicks). Additionally, specific details about his health beyond the 2017 hospitalisation have not been disclosed by the star or his representatives.
Following the approach of structured bios like Michelle Ackerley: Baby, Husband, Mother, Career Facts and Ade Adepitan: Disability, Wife, Family and Career Facts, this guide organizes verified data into clear categories while flagging areas where the public record is thin.
Key perspectives on Donnelly’s public and private lives
“Donnelly’s family generally maintains a private public profile.”
“Reports about health and addiction in the Ant & Dec partnership primarily concern McPartlin rather than Donnelly.”
The contrast between Donnelly’s privacy and McPartlin’s public struggles shapes the duo’s public narrative.
The distinction between Donnelly’s tight-lipped personal life and the high-drama headlines surrounding his partner defines the duo’s public narrative. For fans and media analysts tracking the Declan Donnelly story, the choice is clear: accept the public facts, or chase the private speculation. The former offers a grounded story of a successful career and a stable, happy family. The latter leads only to dead ends and tabloid innuendo. Donnelly has, by all accounts, built the exact life he wanted: a bright spotlight on stage and a closed door at home.
