Guess who! She's the Playboy model-turned-reality star who's not shy about flaunting her enviable assets... but do YOU recognise this blonde beauty?
She first shot to fame on the seventh season of Australia's Next Top Model.
And on Thursday, this former Playboy cover girl shared an adorable throwback photo of herself from her younger years.
Posing with a frog on her shoulder, it seems as though the now 24-year-old, who is currently battling it out in the South African jungle on I'm A Celebrity...Get Me Out Of Here, has always been into the wildlife.
