The couple, who share two children together, met across the ditch 14-years-ago. But Kelly's backstory is a heartbreaking one.
John met Kelly in the years after her first husband, Jon Roe, was killed in a canoeing accident in Switzerland.
"She is a very resilient woman and quite inspiring to be around, someone who I look up to and who I have a lot of respect for," he told the website.
From the start of their own relationship, John knew it was important to keep Jon's memory alive for Kelly.
"Rather than saying, 'No, I need to be separate with Kelly,' I just said, 'I’m going to bring her past partner into the relationship and really make him a part of it all.'"
