The Aussie singer and fashion designer turns 40 on Thursday but insisted that that doesn't mean that she's planning to lower her hem lines just yet.
'I can't understand people when they ask me if I'm worried about hitting 40. It's great that I'm here, everything is getting better,' the mother-of-one told Fabulous magazine.
'Who cares about a few wrinkles? I'm very happy to be here, this is just another chapter of my life... I actually think I may be having a mid-life crisis - instead of getting rid of my short skirts, I'm totally embracing them. I went out and bought myself a black leather jacket. I'm definitely having a rock-chick moment.'
