Mark Feehily has been missing from Westlife’s stage for a long stretch, yet the reporting names surgeries and a lawsuit rather than a single diagnosis. This piece separates confirmed facts from rumour, starting with a medical negligence claim valued at more than £200,000 that Feehily has brought against surgeon Nick Carter (New Zealand Herald (court-record reporting)), and marks where the reporting runs thin on his partner, home and net worth.
Age: 46 · Birthplace: Sligo, Ireland · Band: Westlife (Irish boyband) · Touring status: Stepped back, announced February 2024

Ten data points, one pattern: the firmest facts cover the 2020 surgery and the lawsuit, while his current personal life is almost entirely unrecorded.

Is Mark Feehily still part of Westlife?
Yes, according to bandmate Kian Egan, who says Feehily is still a member of Westlife but lacks the energy to join the band’s current touring schedule (EVOKE, Irish entertainment site).
The break itself is older than the current residency. According to EVOKE, Feehily announced in February 2024 that he would temporarily stand down from all Westlife touring to recover (EVOKE, Irish entertainment site).
- Last Westlife performance: November 2023 (New Zealand Herald, court-record reporting)
- The 25th anniversary run: a 13-night residency at Dublin’s 3Arena in September 2026, without Feehily (The Sun Ireland, entertainment reporting)
- The supplied reporting does not give a full current lineup, so membership should be confirmed through the band’s official channels.
Westlife is keeping Feehily on the roster while the stage moves on without him, so fans should treat membership and touring as two separate questions.
The catch: A band can keep a member on paper while the touring calendar runs without him, and the 2026 dates show exactly that gap.
What is Mark Feehily’s illness?
Reporting does not name a single diagnosis. What it does document is a chain of surgeries and infections that began with a weight-loss operation in 2020.
Feehily underwent a laparoscopic sleeve gastrectomy on August 1, 2020, at Spire Portsmouth Hospital in Hampshire. The New Zealand Herald reports that he developed sepsis days later, was admitted to intensive care and remained in hospital until December 2020 (New Zealand Herald, court-record reporting).
What surgery did Mark Feehily have?
- Laparoscopic sleeve gastrectomy on August 1, 2020 (New Zealand Herald, court-record reporting)
- Total gastrectomy, the removal of the entire stomach, in May 2023 (New Zealand Herald, court-record reporting)
- Four major surgeries in total during the period of his health problems (Extra.ie (Irish entertainment news))
Is Mark Feehily well now?
- Shane Filan says Feehily is “ok” and “taking a step back at the moment” (Classic Hits, music news site)
- Feehily withdrew from Westlife concerts after developing pneumonia in late 2021 or 2022; sources differ on the year (Female First, celebrity news site)
- No supplied source confirms his current health status.
These health details come from press accounts of court filings and interviews, not from a medical record, so no diagnosis should be inferred from them.
The implication: Readers searching for a diagnosis will find surgeries and infections in the record, but no confirmed diagnosis label in these sources.
Who is Mark Feehily’s partner?
The supplied sources do not confirm a spouse. According to Female First, a partner named Cailean O’Neill is the person with whom Feehily welcomed a daughter, Layla. That is a single report with low confidence, and no primary source confirms it (Female First, celebrity news site).
His solicitors have spoken only about the case. Suzanne White, a partner at Leigh Day Solicitors, said the firm represents Feehily in the claim and that he will not comment while proceedings continue (The Independent, UK national newspaper).
- Spouse or wife: not named in any supplied source
- Partner’s name: Cailean O’Neill, in one Female First report only
- Current relationship status: not reported
The catch: The only name in circulation comes from one low-confidence report, so repeating it as fact would turn a single source into a settled answer.
Where does Mark Feehily live?
No verified current residence appears in the supplied sources. His birthplace is Sligo, Ireland (New Zealand Herald, court-record reporting), which describes his background, not an address.
The places that do appear are event locations, not homes.
- Birthplace: Sligo, Ireland
- Surgery location: Spire Portsmouth Hospital, Hampshire, England (New Zealand Herald, court-record reporting)
- Court: the High Court, where the claim was issued (Mathrubhumi English, news on the split trial)
- Not used: tour locations and social profiles, which do not establish where he lives
The implication: Anyone naming a city as his home is filling a gap that the reporting leaves open.
What is Mark Feehily’s net worth?
No supplied source reports a net worth figure. Ground News records that his net worth is not reported in any source it reviewed (Ground News, news aggregator).
The figure that appears in coverage of the lawsuit is the value of the claim, more than £200,000, and not a measure of his wealth (New Zealand Herald, court-record reporting).
Readers who see £200,000 beside his name could take a legal claim value for a wealth estimate, which misstates both his finances and the case.
- Ranking Westlife members by wealth: not verified in any supplied source
The trade-off: Publishing a net worth figure would require a named financial source with a date, and none of the material reviewed supplies one.
Key dates in the record
- August 1, 2020: laparoscopic sleeve gastrectomy at Spire Portsmouth Hospital (New Zealand Herald, court-record reporting)
- Late 2021 or 2022: pneumonia leads to withdrawal from Westlife concerts; sources differ on the year (Female First, celebrity news site)
- May 2023: total gastrectomy (New Zealand Herald, court-record reporting)
- November 2023: last performance with Westlife (New Zealand Herald, court-record reporting)
- February 2024: temporary stand-down from Westlife touring, according to EVOKE (EVOKE, Irish entertainment site)
- June 2025: claim issued at the High Court (Mathrubhumi English, news on the split trial)
- May 28 to July 31 (2026): preliminary split trial window, deciding liability only (Mathrubhumi English, news on the split trial)
- September 26–27, 2026: the lawsuit becomes public through a Sunday Times report (Metro (UK news site))
- September 2026: the Dublin 3Arena residency runs without him (The Sun Ireland, entertainment reporting)
- Late October 2026: Feehily performs “Flying Without Wings” at a wedding in Donegal, after donating a performance prize to a charity auction (Extra.ie (Irish entertainment news))
The split trial window is dated May 28 to July 31, 2026, while the lawsuit reporting is dated late September 2026. None of the reporting reviewed says whether that hearing took place, so its outcome remains open (Mathrubhumi English, news on the split trial).
The pattern: The medical record starts four years before the band’s stand-down was reported publicly, so reading the 2024 announcement as the starting point gets the sequence wrong.
What is confirmed and what is not
Confirmed facts
- Laparoscopic sleeve gastrectomy on August 1, 2020, at Spire Portsmouth Hospital (New Zealand Herald, court-record reporting)
- Claim issued at the High Court in June 2025, valued at more than £200,000 (New Zealand Herald, court-record reporting)
- Feehily’s solicitors at Leigh Day act in the claim against Nick Carter (The Independent, UK national newspaper)
- Westlife’s September 2026 Dublin residency ran without him (The Sun Ireland, entertainment reporting)
What’s unclear
- Current health status and diagnosis
- Whether he returns to touring; no return date appears in the sources
- Partner identity, based on one low-confidence name (Female First, celebrity news site)
- Net worth, with no figure reported (Ground News, news aggregator)
- Outcome of the lawsuit and of the split trial
- Carter’s account: he denies liability, and his defence accepts that a leak occurred, calling leakage a recognised complication in about 1% of cases (PinkNews (UK LGBTQ+ news site))
- Year of the pneumonia withdrawal: 2021 or 2022
The catch: The list of unknowns is longer than the list of confirmed facts, and that is the honest shape of this story.
What the people involved have said
“We are representing Westlife lead singer, Mark Feehily in a medical negligence claim at the High Court against laparoscopic, upper gastro-intestinal and bariatric surgeon Mr Nick Carter.”
Suzanne White, partner at Leigh Day Solicitors, quoted by The Independent (UK national newspaper)
“He is still a member of Westlife. The best way to describe it is, he just doesn’t have the energy to do what we’re doing.”
Kian Egan, Westlife member, quoted by EVOKE (Irish entertainment site)
“He’s ok, he’s taking a step back at the moment.”
Shane Filan, Westlife member, quoted by Classic Hits (music news site)
“All of this really drives home the honest truth that I’m simply not ready to take on a massive world tour yet. My body and my mind need time.”
Mark Feehily, quoted by PinkNews (UK LGBTQ+ news site)
The pattern: The band and Feehily both frame the break as recovery, while the legal side stays silent by design. That split is why the lawsuit and the touring hiatus should not be merged into one story.
Where the record leaves Feehily
The verified record is strongest on the 2020 surgery and the High Court claim, and thinnest on everything that defines a current life: health today, partner, home and money. Westlife’s public messages agree on one point, that Feehily remains in the band while stepping back from the stage. For fans, the choice is clear: wait for the band’s official channels or a court record before accepting new claims about his partner, home or finances, or accept press accounts that no court or band has yet tested.

What this means: Both pieces cover other celebrities’ health and money stories, so they show how similar coverage is framed, not what the record says about Feehily.
