Scorching hot! Jessica Hart shows off incredibly pert derriere and model figure in tiny bikini bottoms as temperatures soar to 42 degrees

She's one of Australia's most successful exports, and Jessica Hart was looking every inch the international supermodel on Friday.

As the temperatures soared to a scorching 42 degrees in Sydney, the 29-year-old brought even more heat to Tamarama Beach, showing off her pert derriere and model physique in a tiny grey bikini.

The Vogue cover girl enjoyed soaking up some rays on the sand, before diving into the ocean for a quick dip, adjusting her bikini bottoms as she returned to her towel.

Goddess! Supermodel Jessica Hart showed off her incredible supermodel figure while splashing around at Tamarama Beach in Sydney on Friday 

She was pictured relaxing with her Luma Cosmetics manager George Moskos and a cute pup as she made the most of the heatwave.

In one snap, the Just Jeans ambassador was seen bending down to fix the sand from her towel. 

In a pose that would be unflattering for many, the model still managed to show off her incredibly toned glutes, before running daintily into the water. 

Revealing her fitness secrets to Gritty Pretty in December, she said: 'I also have a trainer and we do pilates, spin classes or yoga – I like mixing it up. I don’t think your body responds as well when you’re only doing one form of exercise.'

Her luscious blonde locks cascaded in salt-sprayed, free-flowing tresses as she ran toward the waves, tying it up in a messy bun upon her return to the sand.

She also frolicked in the shallows as her abdominal muscles flexed, showing off her taut midriff. 

Upon her departure from the beach, she donned on-trend denim cutoffs and over-sized sunglasses as she headed home.

Jessica has been busy since arriving Down Under earlier this week.

The ambitious beauty launched Luma, a natural cosmetics brand last year, and it appears to have gone from strength to strength since then.

She told POPSUGAR last year that sun protection is by far her highest priority when it comes to summer beauty regimes: 'I’m a big advocate for sunscreen, it’s so crazy what it does for you.'
