Kylie Minogue has beaten all the odds and come back on top with a thrilling comeback tour, however, the triumphant star recently realized it's all about taking slow, baby steps, or you'll simply burn yourself out.
Stylin' Kylie was forced to pull out of a performance with U2 on Monday due to her exhaustion on stage.
The Aussie pop singer - who has beaten breast cancer, after being diagnosed with the illness in May 2005 - was set to join the Irish rockers on stage as a thank you to Bono for performing a duet with her on the second night of her resumed "Showgirl Homecoming" tour in Sydney on Sunday.
However, Kylie - who is still not fully fit following an intensive chemotherapy - had underestimated just how physically demanding the two-and-a-half-hour performances would be and was forced to grudgingly cancel her appearance.
A source told Britain's The Sun newspaper, "Kylie called Bono to explain that she had worn herself out. She is really feeling the physical effects of her return to the stage. He told her to spend Monday resting, get her energy levels fully restored and relax."
The source added, "It wasn't a problem at all. Everyone realizes Kylie is putting herself through the mill for the tour."
Stylin' Kylie's tour has changed significantly from last year's postponed shows in order to accommodate the singer's reduced fitness levels and limit her stress.
Before her first show on Saturday, she said, "I'm as prepared as I can be but I'm not sure that I'll be able to do everything that I did before."
