After just six months of marriage, Myleene Klass has been walked out on by her husband, ex-bodyguard Graham Quinn. He left the 34-year-old TV presenter and their two young children on Myleene's birthday on April 6th. A source close to Klass said: "She's heartbroken. It's an awful situation."

The sudden walk out left Klass to look after their two daughters, Ava Bailey Quinn, 4, and Hero Harper, 1, by herself whilst also having to juggle a busy personal life.

Graham, 38, met Myleene when he became bodyguard for her former pop group Hear'Say, following their success on the predecessor to the X Factor etc Popstars. The couple married in October last year following a five-year engagement, although they were due to marry earlier but this was cancelled due to the arrival of Ava Bailey. The wedding was kept secret - with Myleene breaking the news on Twitter by announcing: "Just married." As little as 16 close family and friends are thought to have been in attendance.

Myleene smiled bravely for the cameras yesterday at Hyde Park's Jubilee Festival, which she is co-hosting, before the news of her split broke. Now that the news of her deteriorated marriage is public, it is expected that she will be allowed time away from her work to concentrate on her personal affairs.
