Gina Stewart, who is regarded as the ‘World’s Hottest Grandma’ is currently competing in the Maxim Cover Girl Competition.

The 48-year-old American model who will be the oldest cover model in the history of Maxim magazine, if she wins, has been campaigning online to secure the cover of the popular men’s magazine.

Gina, who has vowed to fight ageism in the modelling industry proudly flaunted her double-E cup breast implants and curves in a series of photos and videos she has been sharing with her followers.

‘I am so excited to be able to make history and I think the modelling industry needs more age diversity,’ she wrote.

‘I want to set an example for other mothers and more mature women that you can be sexy at any age,’ she continued.

‘I want to inspire women to be confident and go for what they want. I am focused on empowering other women.’

‘I’m just trying to make history,’ said Gina. ‘No woman my age has been on the front cover of Maxim.’

She also revealed that if she wins, she’ll give a portion of the prize money to charities helping sick children and veterans.
