For Kylie's secret is Botox and beauty spa holidays that can roll back the years for any woman -with £40,000 to spare. In the past six months the singer has spent two, seven-night breaks at Spain's SHA Wellness Clinic. Kylie signed up for a range of health treatments, including a macrobiotic diet to help her body recover from the cancer she battled in 2005, and 'Integral Facial Rejuvenation' to reduce her wrinkles. A clinic source said: "She loved it here and sees looking after herself inside and out as a wise investment. She had six months of chemotherapy after her cancer was diagnosed and this clinic not only allows her to hide away so she can have beauty treatments but also makes sure her body is healthy too. "She had lots of massages and hydrotherapy treatments, but Kylie was there for the macrobiotic food and rejuvenation therapies."Kylie, who is dating Spanish model Andres Velencoso, 31, only ate raw fruit, vegetables and brown rice during her stays.
