Naked except for a fur coat, Imogen said: "We have a lot to deal with separately ... It's probably been one of the hardest years of our lives, separately.
"I've got so much family stuff, and there's so much health stuff involved between us.
"We just kind of want to get each other, get ourselves into the best form of ourselves we can be, without kind of just p**ing in each other's pockets.
"We still love each other very much, we speak every day. We still see each other, we deal with things with each other."
"Everyone's like, 'Is there something else?' But not really," she added.
"We haven't been living with each other for quite a few months now. Unfortunately, it's just run its course," he said.
In an interview with Maxim three years after they first met, Imogen revealed that Kyle had declared his love for her just two weeks into their relationship.
"If anything happened to her, I could never be with anyone else," Kyle told WHO magazine in 2013.
In August, the pair moved into a rented home in Sydney's Hunters Hill, however it seemed the writing was already on the wall for their relationship, as a neighbour told Daily Mail Australia this week they had "barely seen" Imogen at the property in months.
