Lately, Casey debuted another transformation - her dramatic weight loss.
Taking to Instagram earlier this year, Donovan reflected on her incredible weight-loss transformation after dropping a huge 23kg in just 15 weeks.
In the emotional post, the singer confessed: 'When Motivation lacks, I look at how far I’ve come and I don’t ever want to go back to that girl in the white singlet!'
'@wlcw.aust has changed my life, not only in shape and size but my mindset.' she continued.
Casey went on to honestly admit: 'It’s not an easy road, (I’m not going to lie) but the payoff is so rewarding! Just to feel better in health and be able to run a little longer each week makes me feel so much stronger in the person I am, and how proud I am of myself for coming this far! It’s a long road and I am going to give it all I got!!'
