'Our connecting wardrobes when we were teens, all the hours you put in to work at such a young age and you, me and our brother Brendan all being so fortunate to have our family and each other,' Kylie reminisced.    

'I could go on and on!!! In short, I love you and I'm so proud of you Mama!!! Happy Birthday!' she continued, alongside photos of themselves in their younger years.

Dannii, who has been working in the entertainment industry for 41 years, admitted in Stellar magazine, that she feared her career was over at age 16, when she left Young Talent Time.  

'Globally, in film and TV and acting, there's so many women of different ages being featured now. There's not that fear of an expiry date,' began Dannii.

'I definitely had that thought at age 16 when I left Young Talent Time. I thought, 'That's it, I'm done'. I'd have to get a normal job.'

Dannii continued: 'You keep working, wondering how long it will go on for, but I'm feeling positive about the acceptance of women of all ages.' 

She first found fame at age 7, appearing on soap operas such as Skyways and The Sullivans.

Following in sister Kylie's footsteps, she signed a recording contract with Australian-based Mushroom Records in January 1989.
