The 42-year-old singer ' who has been dating Spanish model Andres Velencoso for two years ' has considered "various options" in the hope of getting pregnant in the future after treatment for breast cancer in 2005 left her doubtful she is able to have children naturally.

She explained: "I've looked into various options. I don't know if I'm going to go down any of those roads yet, but I do need to look at what might be potential paths that lead to a family. They can do incredible things now, especially in America."

The 'All The Lovers' hitmaker also admitted she is closer to feeling like herself again following her battle with the disease, revealing the illness had such a damaging effect on her she felt like she was trapped in a 'stranger's' body for a long time.

She added to Britain's Glamour magazine: "I don't want to lose any more weight. I just need to get my fitness up. I do feel that then I'll almost be back in my own body, which would be great.

"I felt for such a long time that I was in a stranger's body."
