Kylie Minogue not happy all the time

London: Singer-actress Kylie Minogue accepts she is blessed to have such an incredible career but admits she can become frustrated. She loved exploring her darker side in new film `Holy Motors`.

"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," contactmusic.com quoted Minogue as saying. "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. What face do I show?," she said. In 2005, the 44-year-old was diagnosed with breast cancer and battling the disease left her so ill, she couldn`t even concentrate on watching a movie. "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. Her drive to beat the illness and get well again, stemmed from her desire to return to the stage. "Possibly because I was diagnosed mid-tour, that was my goal, to get back and perform. I just realised that no, this is what I do, and I want to do it better than before," she said. IANS
