Now, cricketing legend Shane Warne has begun 'liking' the busty blonde's Instagram pictures - one of which sees the lingerie-clad mother-of-four posing seductively in her bedazzled bedroom.
Previously, Gina has shared her best beauty tips and tricks with New Idea.
With her golden locks, flawless skin, and toned physique, the 'hot grandma' could fit in among the most glamorous of fashion models.
But this blonde beauty loves nothing more than spending quality time with her four-year-old daughter at her Gold Coast home.
And despite being a single mum to her children James, 27, Casey, 25, Cody, 22, and Summer, four – while also being a nana to her son James’ 10-month-old baby girl – Gina doesn’t have a single grey hair or stretch mark.
The woman dubbed ‘the world’s hottest grandma’ has even knocked out scores of young women, after reaching the semi-finals for the coveted crown of Miss Maxim Australia.

After a traumatic incident two decades ago, Gina sought help from a psychiatrist so she could deal with her emotions.
