Lara Bingle and her husband Sam Worthington enjoy a beach day with their three sons in Sydney

Lara Bingle and her husband Sam Worthington enjoyed a fun family outing with their three children on Sunday.

The couple were spotted spending time with their sons Rocket, five, Racer four, and a baby boy, whose name is yet to be revealed, at Sydney’s Parsley Bay.

The 33-year-old model cut a casual figure in black jeans and a matching coloured T-shirt as she walked along the sand.

Lara tied her blonde locks in a short bun and wore sunglasses to shield herself from the summer sun.

Sam also looked stylish in an all-black ensemble consisting of jeans and a T-shirt as he watched on while his sons Rocket and Racer played on the sand.

After a fun day at the beach, the pair visited a nearby ice-cream stand and enjoyed a treat.

The family-of-five then sat on a rock and relaxed before heading back home.

Lara and Sam arrived back in Australia with their three children, last month. 

Last year, it was reported that Lara was planning to move back to Australia with her husband-of-seven-years and their family.

Lara and Sam have been based in the US with their sons Rocket, five, and Racer for years.

The pair welcomed their most recent addition, a baby boy, whose name is yet to be revealed, in June last year. 

The private couple are yet to reveal the baby’s name and exactly when their son was born.

Lara and Sam began dating in 2013 and married in secret a year later.

The doting mother said in an interview with Marie Claire that she thinks her body was ‘meant to have kids’ and she would ‘happily’ have more in the future.
