Myleene Klass' ex‑husband Graham Quinn: From heroin offences to betrayal on her birthday

Pop star turned TV presenter Myleene Klass has opened up about the heartbreaking moment she discovered her now ex-husband "cheated" on her with a famous celebrity at her own birthday party.

Myleene, 47, shed light on the moment during a podcast episode with Married At First Sight's Paul C Brunson. She revealed on his show, We Need To Talk: "I walked in on him with a famous person on my birthday on a balcony."

The mother-of-three claimed the pair tried to brush off their actions, but she insists "they were unzipping each other". She continued: "I kicked everybody out of the party, including his mum and dad. They went back to Ireland and his dad said, 'He doesn’t get it from me'. I just remember that as being quite a weird thing to say."

Detailing exactly what happened after she spotted the pair "unzipping" each other, Myleene, who shares Ava, 17, and Hero, 13 with her now-ex, admitted life completely fell apart.

Who is Graham Quinn?

Graham and Myleene met when he worked as a security guard for Hear’Say, Myleene’s pop group from the early 2000s.

The pair began dating in the mid‑2000s, welcoming their first daughter, Ava, in 2007 and their second, Hero, in 2011. They married in 2011, but their marriage ended just six months later, with divorce finalised in 2013.

Heroin allegations

Myleene has previously discussed her ex-husband's legal troubles. At one point, he was reportedly arrested in connection with heroin possession and distribution charges.

Speaking to The Standard in 2012, Myleene revealed Graham had been arrested when he was 17 years old for heroin possession in his native Dublin and had jumped bail.

She said at the time: "Before we even considered having a relationship, he was very up-front with me about what he had done. He was young and he got caught up in a bad crowd. I was shocked, but I also respected his honesty and the fact that he didn't make any excuses for his behaviour. Who was I to judge?"

He was fined and given a suspended prison sentence and has since become a patron of the Drugsline charity and talks to children in schools about the dangers of drugs.

Birthday betrayal

In the podcast, Myleene explained: "They weren’t having sex but they were unzipping each other."

Addressing how she felt about her ex-husband's unnamed lover in the aftermath, she said: "I've made peace with that situation now, but for a long time, it was very difficult to see their life.

"Not that I would wish that on a family... I don't know I'm conflicted. My life literally just broke apart very, very publicly and their life, they’ve managed to continue building a family brand on it. It felt so difficult for a long time."

Wedding

According to Myleene, the marriage collapsed within six months. Quinn’s hidden real estate purchase and refusal to sign a prenup made her feel betrayed.

As she described it: "So we’d had the biggest row... I'd asked him why he wouldn't sign the prenup. On the night of our wedding I asked again... He'd actually got a house, a secret house that he'd bought already".

The relationship - and subsequent divorce - was emotionally and financially draining. Myleene said, "All I will say to you is I’ve raised my children single‑handedly, financially, as a sole parent for 12 years".

On the podcast, Myleene added: "My life literally just broke apart very, very publicly... And their life, they’ve managed to continue building a family brand on it and it felt so difficult for a long time".

Looking back on their wedding she said it was the "most miserable" time, and that she cried "the entire reception".
