The Aussie singer may have only had baby Ethan in July with boyfriend Kris Smith but she already wants to add to her family.
She told The Guardian Weekend: 'I've gone from being not being bothered about being a mum to being quite keen to have a second baby.
'For me, the baby idea came from meeting the right man. And now he's here and he's giggling and smiling. It is an incredible thing.'
The 39-year-old added: 'I never thought I was very maternal.
'I was always so busy with work, and a baby just seemed like something I was never going to do.'
