But it’s not all glamour. Me and my big sis Tessie – aka my new full-time stylist – had to get up at 3am to catch our Easyjet flight from London to Nice, so we couldn't wait to jump straight in the sea when we arrived.
We bought four suitcases with us, full of daywear, shoes, jewellery, make up and general holiday stuff that inevitably we wouldn’t need but I'm a typical over-packer.
Plus so many companies had gifted us amazing clothes and products when they found out we were coming To Cannes.
We had a luxury Uber to take us anywhere, plus huge deliveries from Asos, Boohoo, Pretty Little Thing and MissGuided.
Then, once you get to Cannes, there are the gifting suites where you can borrow clothes from loads of designers and jewels from APM Monaco.
It was so lovely to bump into old friends, like Jean-Bernard Fernandez-Versini who works so hard during the festival, and knows literally everyone.
I hadn’t seen him for a while but he’s a good family friend and came to say hi to me and my sister with a big hug and some funny stories when he saw us in a swanky restaurant.
He's on great form right now and in a good place.
But the thing about Cannes is you sometimes bump into old friends – and rivals – too. It happened to me on my penultimate day at an amazing party hosted by jewellery house Chopard.
We were told to meet at our hotel where transport would be provided to take us to a top secret location.
This turned out to be a magnificent mega-mansion up in the hills, lit up with fairy lights and spotlights like a diamond in the sky.
They were all out tonight. I bumped into Lupita Nyongo'o, French actress Marion Cotillard, Julianne Moore, supermodel Irina Shayk and the gorgeous Joan Smalls.
Enrique Iglesias was the entertainment and he is SO hot in real life.
Kendall Jenner was also there but we don’t speak since that, ahem, little incident at an LA pool party a few years ago where she tried to get me thrown out because she didn't know who I was.
Fair play to her, I have to say she looked sensational in her transparent dress but I couldn't believe it when her and her crew gave me the cold shoulder again on as we left our beautiful hotel the Martinez.
The whole day leading up to Chopard was crazy. I went to the suite in the Martinez where Greek couture house Celia Kritharioti was stationed.
Wow – rails of clothes for the celebs to come in and choose from with stylists on hand to offer advice about what could work for your height and body shape.
I adore this designer and wore her to the Fashion Awards at the Albert Hall last autumn.
They had sent me pics of the gown to London before I came down here but it was nothing like what it was in person – the detail was just 'Wow!'
I then spent several hours being pampered in the L’Oréal Glam suite – there was much excitement as Cheryl Cole was arriving too.
They persuaded me to go for a red lip which is quite daring and a first for me. Colour Riche Matte 347 was a game changer. On went the Eylure lashes and we were all set.
This was my moment – I literally had to pinch myself. AP Monaco had sent me an abundance of jewels for the week so Tessie selected some nice drop earrings and a necklace.
I was stoked when I found out Lupita had popped in earlier to borrow some jewels for her new movie too.
Cannes is a celeb-fest the second you hit the famous Croisette boardwalk.
The atmosphere is electric – the place is abuzz with people rushing around, air kissing, mingling, posing, networking and looking over their shoulders to see who is arriving next.
I'm used to being followed around by photographers but this really feels intense.
I do yoga so whenever my body starts to shake with nerves I close my eyes and go to a quite place for five minutes and breathe really deep into my core – always works a treat.
Then I remember that I'm representing Britain on the red carpet – we have so many Americans doing their stuff like Bella Hadid and Kendal Kenner. It’s time us Brits gave them a run for their money!
The first famous face we spotted was the gorgeous actress Julianne Moore, who was surrounded by her entourage of a stylist, personal assistant and security guards.
She flashed me a warm smile as if to say 'You've got this, girl!'
We checked into our hotel The Martinez which has just had a major revamp so it is utterly gorgeous with sea views and beds the size of houses.
Supermodel Petra Nemcova was staying a few doors down the hallway and most of the the rooms were booked up by haute couture fashion houses using them as gifting suites for the stars.
But me and my sis were desperate to see some beach action before the first red carpet so we donned our sunnies and bombed down the hallway.
We couldn't believe it when we passed Cate Blanchett in the hotel lobby – looking effortlessly beautiful. She had her blonde haired little daughter with her who was so angelic.
Cate was wearing a beautiful pale pink suit, nipped in at the waist and gorgeous nude heels that looked like Manolo’s.
What I loved about her was that she smiled at everyone from the hotel staff to little old me – unlike so many other stars!
We stopped to survey the Martinez action, (it all happens here), and took shameless selfies on the Jetty and then went off to a lunch at the beach restaurant.
Even if everyone looks super skinny at Cannes, you'd be amazed how much of it revolves around food.
And the festival is not just about trying to look pretty on the red carpet, it’s about networking and taking meetings and we had a few things lined up.
Day two was my cue for my first exciting appointment in the L’Oréal Style Suite.
The cosmetics brand takes over the ground floor conference room of the hotel and turns it into a full-on glam station for all the stars.
There were four make up stations by L'Oreal and and four more courtesy of luxury French haircare brand Dessange Paris.
It's every girl's dream, you can just walk in looking like you were dragged backwards through a bush and they glam you up from head to toe until you look like a flawless queen.
And of course there are all these amazing beauty experts there to answer all your grooming queries.
There are shuttle cars for VIP’s to take you to the top of every red carpet.
When you step out it’s slightly intimidating – literally hundreds of photographers staring at you but you have to breathe and go and tell yourself, 'Yes we Cannes!'
Day 2 on the red carpet was even busier. I was dressed in a gothic-style see-through black lace gown by Paris couture house Jean Paul Benielli.
No sooner had I stepped on the red carpet than I bumped into the awesome Lupita Nyong’o – wow she looked stunning and every inch the Hollywood superstar and she is SO friendly and adorable.
After the film, we had an invitation from some film millionaire to join a classic Cannes yacht party with charter boats company Alfie Buoy where there was copious amounts of food and cocktails.
It was all so fancy and I mentioned in passing to the crew that what I would REALLY love was a McDonald’s.
So, they sent a speed boat whizzing off to get it and bring it back – boom! – just like that. I tell you it was the best burger I've ever eaten. In Cannes, your wish is their command.
Day 3 came and we headed off to the famous Hotel Du Cap at Eden Roc for another meeting.
All the meetings are always around eating. The pastries in Cannes are out of this world but not good for the tummy.
I wore another beautiful gown by Marco & Maria that evening after they were so generous and sent me five to choose from.
Later that night was the Magnum Alexander Wang party with Bella Hadid.
I have met her a few times and I must say, she is super cool. I sat next to her a few months ago at a Tag Heuer dinner in London so it was nice to see her again.
Tessie and I spotted Abel from The Weekend at the party who is rumoured to be her new boyfriend.
I changed again for this party because I was averaging about five looks per day at this point.
Did I tell you about the free Magnum bar where you could help yourself to as much ice cream and toppings as you wanted? Ice ice baby!
We stayed at the party till pretty late and then headed back to our hotel to celebrate my new single release at midnight – ‘Girls Are Changing the World’.
When I woke up, I was super excited to discover that it had made Spotify’s New Music Friday playlist which for an independent artist is pretty cool and I was over the moon.
We danced until the early hours and hobbled home just before dawn.
Waking up on Saturday morning we pinched ourselves as the whole week seemed surreal.
We just had time to pack in one last lunch date with a Hollywood film executive who wanted to meet to discuss possible film options for my book Pop Girl.
The story is a fictional take on my big break when I handed my demo to David Furnish in a restaurant, who then gave it to Sir Elton,who then invited me to open his Scottish concert to 17,000 people when I was just 13 years old.
We Scots are born hustlers! And surely this is what Cannes is all about.
Before we knew it , Cannes was all over. Being there fuels you even more to work harder and succeed.
Sure, there’s lots of air kissing and BS, but these people have done some pretty incredible and creative things and I really do count my blessings that I had the privilege of being in the same place as them.
As we boarded the EasyJet flight back to London, I put in my earphones, got out my note book and jotted some ideas down for a new song. Until next year Cannes – it’s been awesome!
