The `All The Lovers` singer - who is currently dating Spanish model Andres Velencoso - admits romance isn`t always easy and has learnt over the years what is important and what`s not. She said: "You have to work at love. I have never believed that marriage would be the ultimate. There are people who think a love story should last an entire lifetime. I tell myself it will last as long as it lasts, that way there are fewer disappointments. "I`m wising up. More tolerant, less demanding. I am very happy today because Andres totally respects who I am. Whether I`m stepping off stage looking fabulous or waking up looking a sight, it`s all the same to him. And when I`m spinning out of control for no reason, or feeling totally lost and am asking myself thousands of questions - Who am I? What do I want? Where am I going? - he is there." The 44-year-old beauty - who successfully beat breast cancer after being diagnosed in 2005 - says she`s never been happier and loves being with Andres. She told Britain`s Hello! magazine: "I am healed and very in love, that helps. Andres is handsome, kind and very easy to live with."
