The Hustle star tried to go under the radar with a white cap and a pair of Ray-Ban sunglasses covering her face.

The couple visited the north end of the world famous beach, which is favoured by locals and the LGBTQI+ community.

Rebel was all smiles as she strolled to the beach, wearing a mint green t-shirt teamed with a pair of Givenchy sliders.

While Ramona opted for a lilac fleece jumper, denim shorts, teamed with purple slippers and a Chloe beach basket.

The pair then stripped off to their swimwear – with Rebel showcasing her figure in an all-black suit as she enjoyed a dip in the sea.

Her partner slipped into a pale blue bikini as she revealed her beach body, as the pair cooled off in the water.

The Aussie star then dried off in the sun on their beach towels.

Things appeared to get too hot for Rebel and she decided to pop open their black umbrella for some shade.

Given Rebel’s body transformation, fans have been wondering about the actor’s diet and exercise routine.

In an interview with Apple Fitness+ back in January, the Australian actor revealed how she lost “unwanted body fat,” specifically mentioning a low-impact exercise.

The Pitch Perfect star’s secret? Walking for a solid 60 minutes every single day.

“The doctor said to me, ‘Rebel, the best way for you to lose unwanted body fat is just simply walking,'” the actor said in the interview.

“‘Doesn’t have to be high-intensity, doesn’t have to be uphill, just moderate walking an hour a day.'”
