Erin McNaught definitely works out.

The 33-year-old Aussie model showed off her rock-hard abs at Bondi Beach while taking a dip with her adorable son Evander ‘Van’ Gleave.

Rocking a sporty grey and white bikini, McNaught — who is married to English rapper Example — supervised little Evander as he splashed around in the water.

The one-year-old tot was decked out in a floppy hat and a sun-safe rashie, while his model mum donned a pair of white shades and flashed her toned pins as she carried Evander around in the sun.

The former Miss Universe Australia is now based in the UK with her rapper husband, whose real name is Elliot Gleave. The pair welcomed Evander, their first child together, on December 21 last year.

The self-proclaimed fitness fanatic has been taking to social media since her return to Australia from London to visit her family, documenting the holiday on Instagram.

“Vanny’s first swim in the ocean,” she captioned the below snap.

“He kept pulling his swim nappy off so in the end I gave up, #NudieRun #SunsOutBunsOut #Bondi #VanSpam.”

The trio arrived in Australia last month to spend the festive season Down Under.
