London, June 4 (ANI): Dumped Myleene Klass was devastated to discover that her husband Graham Quinn had already secretly bought and moved into a new flat - just five days after he walked out on her.

Friends said that the heartbroken TV presenter has now realised that he had been planning to leave her for weeks and also that there was no hope of them ever getting back together.

Quinn and Klass had been together for 11 years but he called time on their six-month marriage on her birthday, saying he was not ready for commitment.

Myleene is absolutely devastated and utterly heartbroken. She is still in shock because she had no idea the split was coming, the Daily Mail quoted a friend as saying.

Five days after Graham moved out, she was told by a mutual friend that he had bought a new flat in London. It was the final sucker punch. She feels totally betrayed. How can someone house-hunt, put in an offer, exchange contracts and move in all within the space of five days?

It's impossible. He must have been planning this for weeks, if not months, the friend said.

The popular TV host discovered that her marriage was over on her 34th birthday on April 6.

At first Klass only told close friends and family, hoping she and her husband could work things out.

Since then, the former 'I'm A Celebrity Get Me Out Here' star has refused to cancel any work engagements, determined to remain professional.

She even put on a brave face, smiling as she joined impressionist Jon Culshaw onstage at the Jubilee Family Festival in London's Hyde Park, although she declined to comment on her marriage problems.

Unable to stay in the couple's one-time marital home, she has been staying with friends in North London, while taking care of their two daughters, Ava, four, and one-year-old Hero.

Since the break-up she has also lost over a stone in weight, telling friends that she has lost her appetite.

Myleene has been in pieces and had to put a brave face on things during photoshoots and various TV appearances, a source said.

There have been times when she's been in floods of tears in her dressing room, but simply applied extra make-up, and gone out and smiled for the cameras.

Graham has barely been in touch since he walked out. It seems he woke up one day and realised he didn't want to be married any more, the source said.

Her friends are angry with him as as she's been left holding the babies. It's an awful situation.

Myleene has endured two months of hell and does not deserve this. She thought she had a happy marriage, the source added.

The former Hear'Say singer met Graham, 38, when he became the group's bodyguard. And they married in October following a five-year engagement. (ANI)
