I've been wearing Red Roses since I was 22. Jo Malone London is woven into the fabric of my life, and I couldn't be happier to be working with a brand I love so much.

I'm quite into fitness, and I have a fantastic personal trainer who knows me, knows my body, knows when to push me, and knows when not to push me. She doesn't make me do 20 burpees in a row and instead focuses on strengthening my core, telling me we need to focus on making me into 'a tall giraffe'!

My first fragrance as a kid was Tommy Girl. It was amazing. Wasn't it the thing to wear? And then I remember I stopped wearing it because it was literally like the whole classroom was filled with Tommy Girl.

I try out all the latest beauty products and participate in all the shows. It's pretty magical.

Coconut oil. I rub it through my hair, all over my skin, all over my body. Natural's the better way to go.

Sometimes, fame does scare me. When people know where you are and what you're doing, that can be frightening because I'm such a private person. So I like to try and keep things light-hearted and stay as private as possible.

The best holiday I went on as a kid was to Disney World. I wore the same Minnie Mouse dress for 5 days straight and refused to go on any rides apart from It's A Small World. I think my parents wanted to kill me.

When traveling, I like Urth Caffe in L.A. for eggs Benedict with prosciutto or Balthazar in New York, where I order duck shepherd's pie.

For me, I've always found people who stand up and spritz themselves all over their clothes very odd. I'm a big bath addict, and I get up in the morning, and I have a big bath. But when I get out, and I'm still hot but fresh out of the bath, that's when I apply scent. I just have it on my bare skin; I never apply it to my clothes.

You could say I'm a bit of a nomad.

I always wear Nike trainers and love a hoodie. I have a big black and gold one from Adidas that I'm obsessed with.

I don't have a set way of dressing or a uniform, though I kind of wish I did. But then again, I also love that I can be any sort of character I want - that's a little bit of the actress coming out of me.

I'm not used to going out every single night, which you can do in New York.

Accessories are key - nothing beats a cool Panama hat or statement shades - look to Maison Michel or Miu Miu for inspiration.

I'm obsessed with Jo Malone oils. I think they're so beautiful; they're exquisite. But it's not just the oils; I'm obsessed with their packaging. The beautiful glass bottles that you keep on the side of the bath - they're almost iconic.

Big Anya bag - perfect for stuffing papers in for the plane; Ray Bans - in any shape, I'm hooked!

I really like the Nineties! I want to bring back more of the Nineties, like the 'Spice Girls', 'Empire Records', Chloe Sevigny. I don't think anyone really gave it enough credit.

All I ever wanted was to be a sexy bride, and actually, I think I've turned into a romantic bride.

One trend I always go for is nautical: stripes, navy, rope knot belts, gold buckles.

I like my social media space to be somewhere very positive... I like to just be able to just share any images they see, or a piece of art or an item of clothing, and get to share that with the world.

I'm actually rubbish at selfies. I always feel a bit ridiculous doing it unless I'm with a bunch of friends, where I'll usually stand at the back with a huge grin on my face!

I'm lucky to have a fast metabolism, so I haven't had to exercise much.

Cara, ever since you told me at the age of four that you wanted to be Claudia Schiffer, while you were naked in the bath with a sponge on your head, I knew you were destined for great things.

'The Five People You Meet in Heaven' by Mitch Albom - I read it in eight hours and blubbed my eyes out when it finished. I've thought about the story every day since.

I'm a bit of a bed head: I'm always running around with no make-up on and my hair in a mess, but my nails are one thing I do love to keep looking nice, so it's rare to see me without it.

Having hibernation weekends where I just sleep for hours on end. Working out when you have those spare moments. All of that is very important.

When I was about 4, my mum had a lime-green Versace jacket with massive shoulder pads, and I remember thinking, 'Why does her head look so small? Why is she doing that to herself?' But she loved it!

As soon as I get on the plane, I go straight to the bathroom and give myself a little minifacial. MV Organic Skincare does a rose oil spray that is absolutely gorgeous and amazing.

She is such a doer, Cara - she is so ambitious. She has always known what she wants, and she's a hustler. Sometimes I call her, and I'm like, 'You need to help me hustle,' and she is like, 'Come on!'

Sometimes when I need something really nourishing, I'll use the Creme de la Mer night cream - it leaves my skin looking beautiful. I don't go too far on my make-up because I have to wear it so often for work, so I'm quite low key.

The whole working-in-an-office thing was a dream for me - I never get to do it! I'm secretly very organised and obsessed with stationery, especially staplers and post-its, which I know is a little weird.

Attack your lashes with the wand. I think there's nothing wrong with doing that.

I'm more of a handbag girl; my guilty pleasure is bags. I don't even have a clue how many I own.

When I'm in the U.K., I have a personal trainer who is wonderful, and she's hard-core and makes sure I get up in the morning and go.

It would be ridiculous for me to say I am unlucky, but, like any other family and any other girl, I've had my ups and downs.

I think the first outfit that really kick-started my relationship with Chanel means a lot to me: it was a black, sort of Studio 54-inspired jumpsuit with gold stars all over it, and I wore that, and that's how my relationship with Chanel began, so, you know, it has sentimental value.

I'm all about a big lash. I love a good mascara. I use Tom Ford lipsticks. I think he has the most vibrant colours, especially pink or orange or vampish reds, and that's about it.

I love to shut out the world sometimes and hibernate.

We have all learned that addiction and mental illnesses are illnesses, and I think a lot of people overlook that it is a chemical imbalance; it's like cancer, a sickness, and people need to see it as that.

I love working with Chanel, and long may it reign, to be honest. I hope it lasts forever.

I love all girl squads. I'm all for, like, girl power and friendship, and I'm all about that.

My mother is the bravest human being I've ever come across.

I never dress up too much on holiday, but I do spend money on good sandals from labels like Aquazzura.

Look after yourself, get rest, get a facial, get a hair treatment, eat really well, work out, get a personal trainer. And that's really the key: to take care of yourself and not burn out.

Pubs would be number one. And black cabs and cabbies - moody cabbies always crack me up. And the other thing I love is the parks: the parks around London don't get enough airtime - I think they're sensational, and when spring hits, the first thing I'll do is go to the park.

When it comes to work, I'm not competitive at all. Having Cara as my baby, I had to learn quite quickly that I couldn't be competitive because I had a sister who meant more to me. And I knew she was going to be brilliant, so I had to become very aware of not comparing.

I always pack lots of loose linen shirts and denim cut offs, Converse, vintage Reformation sun dresses, gold jewellery, and statement shades. Plus a trunk full of swimwear, of course.

I'm pretty adventurous - the more wacky, the better! Sometimes I'll want to look chic, but lots of the time, I'll wear really mad colours and patterns, as it's just more fun.

I always have an item in mind that I want to wear; then, the next day, I put it on, and I love the 20-minute rush of frantically tearing clothes out of my wardrobe to go with it. And I honestly feel that's the best way to do it; there's no method to my fashion madness so to speak.
