Hatta girl! Isla Fisher shields her fair skin beneath a wide-brimmed fedora as she enjoys hike in the Los Angeles hills

She's Australian and knows the importance of slip, slap slopping. 

And staying loyal to her roots, actress Isla Fisher, 39, ensured she covered up from the unforgiving Los Angeles sun with a wide-brimmed hat. 

The red-head mother was spotted working up a sweat hiking in casual wear and a fedora on Sunday as she chatted to a pal.

Showing off her toned legs in three-quarter black leggings, the former Home and Away star also wore a loose white vest and a light blue shirt.

She teamed her look with grey and orange trainers and shielded her eyes from the glare of the sun with sunglasses.

Isla, who was make-up free, layered a variety of necklaces including a blue beaded piece.

She seemed locked in conversation with her pal on the walk and carried just a bottle of water.

In April, she gave birth to her and husband Sacha Baron Cohen's third child, Montgomery Moses Brian.

The couple, who married in France in 2010, also share two daughters, Olive, seven, and Elula, four.

Isla has a few films on the cards for this year and 2016, including the horror flick Visions, and the comedies Grimsby and Keeping Up With The Joneses.

In June, she was seen on the set of Keeping Up With The Joneses looking toned in a gold bodycon dress.

Last year, she told Fitness Magazine how much weight she put on while pregnant, saying: 'I gained 65 pounds (30 kg) with my first baby and 70 (32kg) with my second.' 

In 2013, she told Women's Health UK she enjoys hiking to maintain her figure.

She also said breastfeeding helped her shed the post baby weight from each pregnancy.

'Breastfeeding – that’s my big slimming secret! That and Spanx,' Isla said. 

'Any time anyone compliments me on my figure, I’m wearing my Spanx undies.'  

That same year, she also spoke to Gotham Magazine about taking time off to have a family. 

'I took three years off. It’s not like you’re taking a break and looking on IMDbPro to see your StarMeter falling,' Isla said. 

'You’re doing the most important, incredible thing.'
