Kylie's tour may be hazardous to her health

Kylie Minogue has luckily made a full recovery from her bout with breast cancer and is determined to get her career back on track. But is the singer, who will take the stage Saturday night in Sydney for her rescheduled Showgirl tour, working herself too hard?

According to London's Daily Mail, Kylie was able to be so brave throughout her breast cancer treatments because she was visualizing herself on stage again. In order to make that fantasy a reality, she has been preparing, sometimes six hours a day, with her dancers. She has also been boxing and working with a personal trainer and Vibrogym exercise machine (a device also favored by Madonna). And Kylie is also eating "super-foods" and drinking a broccoli smoothie each day.

A Showgirl tour insider told the Daily Mail, "Kylie is a perfectionist and, as usual, she is all over everything. She used to have this ferocious temper, but now it's more of a drive to succeed again, which is very infectious. She won't discuss the cancer, or the past, she just refuses to go into it. It's all about living in the present, and that means really going for it."

But Kylie's determination may be at the cost of her health. Her boyfriend, French actor, Olivier Martinez, and her mother, Carol, are both concerned that it may be too soon for Kylie to jump back into touring. A source said, "They have both told her that she is in danger of going too far."
