• Myleene Klass caught her ex-husband cheating with a celebrity on her birthday.
• The other woman built a career on family values. Quinn blamed alcohol for the incident.
• Their marriage lasted only six months. 
• She has since moved on with fiancé Simon Motson.

Myleene Klass recently discussed a devastating betrayal that shattered her life in a highly public way. The TV presenter and musician shared that she discovered her ex-husband, Graham Quinn, in an inappropriate situation with a famous celebrity on her birthday.

Speaking on Paul Brunson’s We Need To Talk podcast, she shared,

“I walked in on him with a famous person on my birthday on a balcony”.

The unnamed woman, who built a career on “family values,” was allegedly undressing with Quinn at Myleene’s own party.

The Shocking Birthday Betrayal

Myleene’s world shattered when she discovered her then-husband in an intimate moment with another star.

“They weren’t having sex, but they were unzipping each other,”

she recalled.

This incident took place in her own home during her celebration. “I’m in my house, it’s my party,” she highlighted. Upon confrontation, both Quinn and the celebrity claimed, “It’s not what you think,” to which Myleene retorted, “It is what I think”.

Enraged, she expelled everyone, including Quinn’s parents. His father’s cryptic remark, “He doesn’t get it from me”, left her baffled.

A Marriage Doomed from the Start

Klass admitted ignoring red flags, including Quinn blaming alcohol for the cheating.

“He said it was the drink,”

she revealed.

Despite doubts, they married in 2011. She later confessed,

“I was sobbing in the bath the night before… I knew it wasn’t right”.

The union lasted just six months.

Quinn allegedly hid assets, even buying a secret house before their split.

“He’d actually got a house… When that came through, I was reeling,”

she said.

Life After the Scandal

The fallout was brutal. Myleene spiraled into alcohol dependency, drinking by 11 AM.

“Finances were spiralling… I thought I’d lose everything,”

she admitted.

Yet, she rebuilt her life, focusing on her children.

“I’ve raised my kids single-handedly for 12 years,”

she stated.

Now engaged to PR guru Simon Motson, she’s found happiness. Reflecting on the unnamed celebrity, she said,

“They’ve managed to continue building a family brand… It felt so difficult”.
