Former British pop star Myleene Klass has moved a step closer to divorcing her husband Graham Quinn after a court gave the green light for their split to become official. The TV presenter's marriage crumbled on her 34th birthday on 6 April, 2012, when the bodyguard walked out just six months after their wedding. The divorce was given the go-ahead on Tuesday (23Apr13) when a judge at London's High Court signed off a decree nisi, granting the order on the grounds of Quinn's "unreasonable behaviour". The marriage will be officially dissolved in around six weeks' time when the divorce will be finalised by the issue of a decree absolute. The former Hear'Say star dated Quinn for more than 10 years before they married in October 2011. They have two daughters together, five-year-old Ava and Hero, two.
