Myleene Klass' husband has walked out on her after just six months of marriage.
Former bodyguard Graham Quinn left the TV presenter and their two young children on her birthday, April 6.
A source told The Sun newspaper: "She's heartbroken. It's an awful situation."
Myleene is said to have been devastated by Graham's actions, as she thought their marriage was going well.
Another source said: "Their wedding was the happiest day of her life but now it's all over.
"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."
Former 'I'm a Celebrity... Get me out of Here' star Myleene had been with Graham for 11 years and they have two children together, daughter Ava, four, and son Hero, one.
Since Graham walked out on her, Myleene has been juggling her work commitments with looking after both children on her own.
The source added: "Graham has barely been in touch since. It seems he woke up one day and realised he didn't want to be married anymore.
"Her friends are angry with him, especially as she's been left holding the babies. It's an awful situation.
"The past months have been the hardest of her life.
"She now realises there is no chance of them getting back together. But even two months later she's shocked at the sudden way he left."
Despite her heartbreak, Myleene put on a brave face yesterday (02.06.12) as she co-hostedHyde Park's Jubilee Festival in London.
