The `All The Lovers` singer - who has been dating Spanish model Andres Velencoso since October 2008 - admits their careers often keep the couple apart, but separation never causes them any problems.
She said: "We try not to leave it too long between seeing each other. But he`s used to travelling, I`m used to travelling. That`s how the relationship started. It works for me and I think it works for him.
"Do I prefer it? In a way, to have time to do your own thing, to be compartmentalized like that, yes. When I try to do everything at once, it`s when I have a meltdown."
The 42-year-old star is still unsure whether she wants to get married and relies heavily on her close pal Will Baker - who she dubs her `Girl`s Best Friend` or GBF - for support.
She explained: "What I may have said is marriage might not be for me.
"I think the 2.4 family is down the drain these days. Every girl has to have her GBF. In my life it has to work."
Kylie is particularly relieved that Will has bonded with Andres as her friend is never afraid of telling her what he thinks of her romances.
She explained in an interview with the Sunday Times newspaper: "They like each other. We all met the same day, which helped. Before that I dated some guy for a bit and Will absolutely bristled and still goes on about it. It`s sweet, I guess."
