Graham Quinn: Myleene Klass’s Ex-Husband and the 2025 Cheating Allegations

Few ex-husbands of a pop star stay out of the spotlight as consistently as Graham Quinn — a former security guard for Hear’Say who married Myleene Klass in 2011 — until a cheating allegation from her in August 2025 changes everything, though his friends deny the charge. The challenge is untangling the documented record from the allegations, because in this story the two keep getting blurred.

Ex-husband of: Myleene Klass ·
Children: 2 (Ava and Hero) ·
Myleene’s current partner: Simon Motson (engaged) ·
Occupation (during marriage): Security guard for Hear’Say ·
Recent controversy: Cheating allegations (August 2025)

Six facts keep showing up across the coverage, one pattern: the older the fact, the better documented it is. Everything about Quinn after the divorce is thinner, and the table below marks where the record ends.

Why Did Graham Quinn Leave Myleene Klass?

The divorce file is honest about the outcome and silent on the causes. A court granted a decree nisi after finding the marriage had broken down irretrievably, and the hearing lasted less than two minutes (BBC News court report). The fuller story, told by Klass to several outlets over the years, is about what happened before and inside the marriage.

What triggered the separation?

• Klass has said she suspected Quinn of infidelity before the wedding (Metro’s account).
• She described catching him with an unnamed famous person on a balcony during a birthday celebration before the ceremony (The Mirror).
• She said Quinn apologised and blamed alcohol for the incident (Entertainment Daily).

Despite those red flags, the wedding went ahead in 2011, with roughly 16 guests. Months later, reports said Quinn left on Klass’s 34th birthday, 6 April 2012 — an account he disputed (HELLO!).

Klass later said she also suspected further episodes while Quinn worked away from home (The Mirror). In 2024, she described nearly calling off the wedding the night before it happened (Metro).

By the time the couple separated, the gap between the public image and the private record was already wide.

What are the cheating allegations from 2025?

In summer 2025, more than a decade after the divorce, Klass repeated the infidelity claim publicly and said she had “receipts” to prove it (Entertainment Daily). Her account echoed the balcony story from before the wedding, and she framed the alleged affair as the reason the marriage could not survive.

• No third party has been named in reliable reporting, and the available coverage does not support identifying one.
• The allegations concern events that allegedly took place before the wedding, not during the divorce.
• No legal complaint, police report, or court filing connected to the claims has been reported.

That last point matters: if there is evidence, it has not yet entered any formal public record.

Did Graham Quinn respond to the claims?

• Quinn has not made a direct public statement in the reporting covered.
• His friends have denied the allegations and pushed back on the narrative (The Mirror).
• No interview, statement, or social-media post from Quinn himself has appeared.

The result is a one-sided public record: a detailed accusation from Klass, a rebuttal from people around Quinn, and silence from the man at the centre.

Why this matters: after more than a decade out of the headlines, Quinn’s public identity is now being redefined by an allegation he has not directly answered — which makes the absence of his own voice one of the most significant details in the story.

The pattern: the public record holds only the legal outcome, not the private causes.

Who Is Graham Quinn in a Relationship With?

The most common question about Quinn is not who he was, but who he is with now. The public record has no confirmed answer.

Does Graham Quinn have a new wife?

• No reliable report confirms a new wife, and none of the available coverage names one.
• No engagement or wedding announcement tied to Quinn has been reported.
• Quinn has not spoken publicly about his personal life in the recent coverage.

The phrase “Graham Quinn new wife” surfaces in search suggestions and social chatter, but it rests on no verifiable evidence.

Is he associated with Rochelle Humes?

• A social-media rumour briefly linked Quinn to Rochelle Humes.
• No credible publication has reported the link as fact.
• Neither party has commented publicly.

The rumour appears to have spread through unverified posts rather than journalism.

What is his current relationship status?

The most accurate public answer is “unconfirmed.”

The trade-off: Quinn’s privacy keeps him out of the press, but it also means every claim about his personal life — sympathetic or damaging — goes unchecked.

The catch: in the absence of Quinn’s own voice, every claim about his personal life — sympathetic or damaging — goes unchecked.

Who Is Myleene Klass’ Partner Now?

While Quinn’s private life is opaque, Klass’s is on the record. The relationship that followed her marriage has been public since it began.

Is Myleene Klass still with Simon Motson?

• Klass has been with property developer Simon Motson since 2020, and the couple became engaged in 2022 (The Mirror).
• No reliable report suggests the engagement has ended.
• The couple has kept details of their life together mostly out of the tabloid glare.

For a public figure, Klass has managed to keep this relationship relatively quiet; the headline facts are the long timeline and the engagement.

Who is Simon Motson’s ex-wife?

• Motson is a property developer and has been married before.
• His ex-wife is not named in the coverage reviewed.
• He keeps family details private and was not a public figure before meeting Klass.

The public record simply has no reliable details about Motson’s first marriage.

Are Myleene and Simon engaged?

• Yes — the engagement was reported in 2022 (The Mirror).
• A wedding date has not been publicly announced.
• The engagement remains the most recent status update in the public record.

The pattern: Klass’s romantic life is documented because she is the public figure; Quinn’s is not, because he stepped away. That asymmetry, more than any legal outcome, explains why this story reads so unevenly from both sides.

How Many Husbands Has Myleene Klass Had?

The short answer is one. Klass has not remarried since her divorce from Quinn.

Who was Myleene Klass’ first husband?

• Graham Quinn, who worked as a security guard for Hear’Say during Klass’s pop-star era.
• The couple married in 2011 in a small ceremony with about 16 guests (The Mirror).
• The marriage ended in divorce in 2013 (BBC News).

A similar dynamic — a relationship that becomes public property — shows up in Ricky Martin’s personal life story.

How many children does Myleene Klass have?

• Two daughters: Ava and Hero.
• Both girls were born during Klass’s years with Quinn.

Do Myleene Klass children see their dad?

• Co-parenting arrangements are private, and neither parent discusses them publicly.
• Quinn reportedly sees his daughters intermittently, though the frequency is not documented (The Mirror).
• No formal custody details have entered the public record.

The catch: “how many husbands” has a definitive answer; “how involved is their father” does not, and no court file or interview resolves it.

The implication: ‘how many husbands’ has a definitive answer; ‘how involved is their father’ does not.

What Does Myleene Klass’ Ex-Husband Do?

The job title everyone remembers is security guard — and it is the last verified one on record.

What was Graham Quinn’s job during the marriage?

• Quinn worked as a security guard for Hear’Say, the pop group that made Klass famous.
• The role put him in Klass’s orbit before the relationship became public.
• It is the only occupation reliably tied to him in the available coverage.

During the Hear’Say era, Quinn was a background figure in the band’s story, and he stayed one after the relationship ended.

What does he do now?

• No verified current occupation is on public record.
• Quinn has given no interviews about his work since the divorce.
• His professional life after Hear’Say is essentially undocumented.

The honest answer is that “what he does now” is not a matter of public record — and any claim to the contrary is speculation.

Is Graham Quinn “on the run”?

The implication: the less Quinn says, the easier it is for others to write his story — and the harder it is to correct anything they get wrong.

• For more on how a private life becomes a public headline, see Michelle Dockery’s baby, fiancé’s death and new marriage.

The pattern: Quinn’s silence leaves a vacuum, and every rumour — from ‘on the run’ to ‘new wife’ — fills it differently.

A Timeline of the Marriage and Aftermath

Four dates anchor the public record of this relationship; everything after the divorce is contested, rumoured, or private.

What this means: the divorce itself was quick and quiet; the 2025 allegations are a later, separate event that has been grafted onto an old story.

Confirmed Facts vs What’s Unclear

The record splits cleanly into two piles: what is established by court or contemporaneous reporting, and what depends on memory, allegation, or silence.

Confirmed facts

• Graham Quinn was married to Myleene Klass, and they have two daughters, Ava and Hero (The Mirror).
• The divorce was granted in 2013 after a court found the marriage had broken down irretrievably (BBC News).
• Klass is now engaged to Simon Motson (The Mirror).
• The cheating allegations became public in August 2025 (Entertainment Daily).

What’s unclear

• Exactly why the marriage broke down.
• Whether the 2025 cheating allegations are true.
• The identity of the alleged third party.
• Quinn’s current relationship status and occupation.
• How often he sees his daughters.

The catch: the older the fact, the better documented it is; everything after the divorce is thinner.

What Myleene Klass and Quinn’s Friends Have Said

In the absence of a direct statement from Quinn, the public record is built from Klass’s account and the rebuttals from people around him.

Myleene Klass has said she caught Quinn with an unnamed famous person on a balcony during a birthday celebration before the wedding, and that he later apologised, attributing the incident to alcohol.

Friends of Graham Quinn have denied the cheating allegations and hit back at the narrative, according to reporting that quotes people close to him.

Klass has said she has “receipts” proving the infidelity and has indicated that doubters will be shown the evidence.

The implication: even the evidence in this story is a promise, not a disclosure — which is why the public is being asked to take sides on trust.

The Bottom Line

For Graham Quinn, the cost of silence is that the story now belongs to everyone but him: friends speak for him, headlines define him, and an alleged balcony moment from more than a decade ago has become his most searched association. For Myleene Klass, the stakes are just as concrete — if the receipts she references are released, the question of whether Quinn cheated stops being a matter of belief; if they never appear, the allegation remains an allegation. For Klass, the choice is binary: publish the evidence and settle the story, or keep it private and leave Quinn’s public record as contested as it is today.
