Myleene Klass Says She Caught Her Then-Fiancé Graham Quinn and a Famous Woman Unzipping Each Other at Her Own Birthday Party, and Still Married Him

Myleene Klass says she threw everyone out of her birthday party, including Graham Quinn’s parents, after finding her then-fiancé with an unnamed famous woman. “They weren’t having sex, but they were unzipping each other,” she recalled on Paul C. Brunson’s We Need To Talk podcast in July 2025.

Klass said Quinn and the woman both told her, “It’s not what you think.” She said Quinn blamed the incident on alcohol, telling her “it was the drink.”

After about 10 years together and 2 daughters, Klass and Quinn married in October 2011. Klass said she “wasn’t allowed to plan a wedding” and “literally cried the entire reception.” They separated about 6 months later.

Klass hasn’t publicly named the woman, whom she said later built a “family brand.” A friend of Quinn called Klass’s wider claims “fantasies”; that was the friend’s response, not a denial of the birthday-party account from Quinn himself.
