The Miss Universe Australia was seen pushing son Ennio, two, in a pram as they collected her eldest son Evander, five, up from school.

Wearing a pair of short shorts in the warm weather, the mother gave a leggy display as she head out.

Erin added to her look with white sneakers, a grey singlet and a white crossbody bag and opted for minimal makeup and a messy top bun.

Making sure her youngster was protective from the sun, she dressed little Ennio in a large bucket hat.

Erin has previously mentioned that her two children, with rapper husband Example, were one of the main reasons she chose to sign up to appear on SAS Australia.

‘I want to show my boys that women and mums can do anything they put their minds to,’ she told The Sunday Telegraph last month.

She also added that she hopes her children form relationships with girls/women based on strength of character.
