From his early days on Byker Grove to the helm of I’m a Celebrity…Get Me Out of Here! alongside Ant McPartlin, he’s become one of the nation’s most recognisable faces.

This article separates fact from rumour across his career, family and health.

Six key biographical facts, one pattern: Declan Donnelly’s life is almost entirely public, yet his health and his 1990s relationship remain the two areas where gossip often outruns evidence.

| Birthplace | Newcastle upon Tyne, England |
| Height | 1.73 m (5 ft 8 in) |
| Spouse | Ali Astall (m. 2015) |
| Children | Two |

What illness does Declan Donnelly have?
Declan Donnelly has not publicly disclosed any major physical illness. In early 2026, he did speak about a long‑term mental‑health challenge. According to Yahoo Style UK (lifestyle news platform), Donnelly described feeling that he can “never sit down” because of persistent anxiety. Ground News (news monitoring service) reported that he undertook therapy and now speaks about low‑level, constant anxiety.
Donnelly’s openness about anxiety normalises a condition that affects one in six British adults every week. His disclosure, made after years of silence, may encourage others to seek help.
Ant McPartlin’s health issues
Donnelly’s on‑screen partner Ant McPartlin has been open about his own battles with addiction and mental health. In 2018, McPartlin took a break from television after a drink‑driving incident and later spoke about depression and anxiety. The pair’s shared vulnerability has strengthened their public bond, but each man’s health trajectory is separate.
Declan Donnelly’s own health history
Apart from the anxiety disclosure, Donnelly has no known chronic illnesses. A low‑confidence social‑media claim that he was diagnosed with osteosarcoma at age 15 is unsupported by any credible medical or entertainment source. Daily Star Showbiz (tabloid, low credibility) published the rumour, but no hospital record, family statement or mainstream news outlet has confirmed it.
The implication: Donnelly’s health narrative is overwhelmingly about mental wellness, not physical illness. The osteosarcoma story appears to be a fabrication and should be treated as an unsubstantiated rumour.
How many children has Declan Donnelly got?
Donnelly has two children with his wife Ali Astall: a daughter born in 2014 and a son born in 2015. HELLO! (lifestyle magazine) notes that the children are rarely pictured publicly, reflecting the couple’s desire for privacy.
His daughter born in 2014
Their first child, a daughter, arrived in 2014. Donnelly took a brief paternity leave from I’m a Celebrity…Get Me Out of Here! and returned to work soon after.
His son born in 2015
The family expanded the following year with a son. Donnelly has said in interviews that fatherhood changed his perspective on work and made him more selective about projects that take him away from home.
What this means: Donnelly has built a stable family nucleus in the years since marrying his manager. The rapid back‑to‑back births suggest he and Astall planned their family deliberately despite high‑pressure careers.
Why did Clare Buckfield and Declan Donnelly split up?
Donnelly dated actress Clare Buckfield from 1993 to 2001. Famous Birthdays (celebrity database) reports that the couple grew apart as their television careers became increasingly demanding. Neither party has given a detailed public explanation.
Who is Clare Buckfield?
Clare Buckfield is an English actress best known for playing Natalie Lambert in the children’s drama The Queen’s Nose. She met Donnelly on the set of Byker Grove.
Declan’s other past relationships
After the split, Donnelly was briefly linked to a few co‑stars but remained largely single until he began a professional relationship with Ali Astall, who was his talent agent. They married in 2015.
The pattern: Donnelly’s most serious long‑term relationships all involve women he met through work – a common theme for entertainers whose social world is dominated by production sets and studios.
How many times has Declan Donnelly been married?
Donnelly has been married once, to Ali Astall, on 1 August 2015. HELLO! (lifestyle magazine) covered the wedding, which took place at a private ceremony in the UK.
His marriage to Ali Astall
Ali Astall was Donnelly’s manager at James Grant Management for many years. Their professional‑to‑personal transition is well documented. They now jointly manage their two children and Donnelly’s career schedule.
Previous marriages
Donnelly has no previous marriages. Unlike many public figures, he avoided early‑career matrimony and settled down in his late thirties.
The trade‑off: Marrying his manager gave Donnelly a partner who intimately understood the demands of his job. It also blurred the boundary between business and private life – a trade‑off that has clearly worked for the couple given their decade‑plus marriage.
What happened to Declan Donnelly?
In 2024, Donnelly and McPartlin signed new contracts with ITV to continue hosting Britain’s Got Talent and I’m a Celebrity…Get Me Out of Here!. Reports from Rotten Tomatoes (review aggregator) confirm no major personal tragedies or career breaks.
Recent news and updates
In April 2025, Donnelly recorded a video message praising a schoolboy who had written a story about Ant and Dec. The clip was shared by BBC News (UK public‑service broadcaster) and showed his characteristic warmth toward fans.
