The 29-year-old model has recently partnered with the French skincare company, and she has admitted she relies on a variety of cosmetic products from the brand, including their Masque Crème Hydratant, Resveratrol Lift Face Lifting Soft Cream and their Vineactiv Energizing and Smoothing Eye Cream, although their part-toner and part-serum product, which helps to achieve a smooth and glowing complexion, is her ultimate favourite.

The blonde beauty - who is expecting her first child with her fiancé Jason Statham - shared the news of her essentials on her Instagram Story, which only lasts for 24 hours on the photo-sharing site.

Alongside a photograph of a variety of products lined up alongside one another, she wrote: "Just a few of my favourite skincare products @caudalie (sic)."

Whilst an image of her clasping at a clear bottle of the Beauty Elixir, read: "My secret weapon for a smooth & glowing complexion! The Beauty Elixir @caudalie (sic)."

And the 'Mad Max: Fury Road' actress is "very happy" to have joined forces with the label, which she has credited as her "favourite natural skincare brand".

Alongside a picture of her posing with one of the products, she wrote: "Very happy to be partnering with one of my favourite natural skincare brands @caudalie! (sic)."

Meanwhile Rosie, who joined forces with Marks and Spencer in 2012 to launch her lingerie line titled Rosie for Autograph, is set to unveil her first swimwear collection for the longstanding retail brand in April.

The British star shared a string of images of her in a one-shoulder bikini whilst swimming on her photo-sharing site to confirm the news.

She captioned the posts: "#RosieForAutograph Swim coming April 2017!

"Very excited to announce the launch of #RosieForAutograph Swim coming April 2017 @marksandspencer! (sic)."
