Kylie, who was forced to tell fans on her 'Showgirl Homecoming' tour she was too ill to carry on after contracting a respiratory-tract infection earlier this year, said: "I was fresh out of treatment when we started that tour. I was terrified and really doubting whether I had made the right decision to go on the road in the first place. I relaxed as time wore on, but that was scary, that moment. And there have been moments since then.
"Your body, your muscles have a memory of the way it was when you were sick, and there are definitely times when I float back to that place. I had migraines a few weeks ago, and I just went, 'Yeesh - no, please.' "
