I'm not happy: Kylie Minogue

The 44-year-old 'Spinning Around' singer said that she is blessed to have such an incredible career but she often becomes frustrated, reported Femalefirst online.

"No one's shiny and happy all the time. There are other sides of me that an experience like this has allowed me to explore. My persona is 'Kylie'. As soon as I step out of my house I have that projection of me. But that isn't necessarily who I am," Minogue said.

In 2005, the singer was diagnosed with breast cancer and battling the disease left her so ill, she couldn't even concentrate on watching a film.

"Lots of friends sent me DVDs and I just said, 'I can't concentrate for a whole film.' A trip to the shop for a drink was a massive excursion," she added.
