The 29-year-old model - who first collaborated with Marks and Spencer, also known as M&S, in 2012 when she released her lingerie line Rosie for Autograph - has revealed if she could stock her closet with multiple versions of the same product it would be a pair of jeans, winter boots and underwear.

Speaking about the essential garments she could wear forever, she said: "Jeans, black ankle boots and lingerie."

And the blonde beauty has revealed due to her busy schedule and being away from home, she is relying on Elle Macpherson's Super Elixir to make drinks filled with vital nutrients to keep her going.

She explained: "As I'm on the road, it's not in my fridge, but I just got Elle Macpherson's Super Elixir, which I just started using. It's a green powder, put it in with water or coconut water and it has all your supplements - nutrients, and vitamins - and it actually tastes delicious! I can't believe it. She just sent it to me."

And the 'Mad Max: Fury Road' actress - who is currently engaged to actor Jason Statham - has revealed there are specific things she will prepare for and work out even more for to ensure she is in great shape, although she wants to feel she is on top form "all the time".

She explained to Elle magazine: "There are very few things I feel I get in specific shape for, I want to feel strong and fit always.

"For me, if I have a lingerie shoot or a swimwear shoot I'll adjust my diet for a few days beforehand, and just make sure I'm not eating big burgers, or reaching for the bread basket in the run-up.

"I want to feel in shape all the time."
