While the couple – who have been together for 11 years – only married in October following a five-year engagement, Quinn is said to have shocked Klass by suddenly claiming he no longer wanted to be married.

“Myleene had no idea that Graham was going to leave her. They only got married a few months ago and she thought everything between them was great. It came as a massive shock to Myleene and she’s heartbroken,” a friend of the pair told The Sun.

Friends are puzzled by the situation and say Quinn has barely been in touch since he cruelly walked out on Myleene’s birthday.¬†However, despite her heartbreak, Klass put on a brave face for a family day out with her girls as she presented the Sainsburys Jubilee Family Festival in London’s Hyde Park on Saturday, the Daily Mail reported.
