“Always keep wiping your face with towels when you work out because I find that the more I exercise, that's when I have my breakouts. You've got to keep the sweat off because the pores are open when you're hot and can get clogged.”

“I always have Giorgio Armani's Luminous Silk Foundation, Bobbi Brown's Jenna lipstick, and my Estee Lauder Double Wear Concealer.”

“I don't wash my hair very often. Once a week if I can. Because the more you wash it, you end up stripping out the natural oils. What I like to do is just rinse out the products that I've used during the week and then put leave-in conditioner in and let it dry naturally.”

“I find my vocabulary is quite a lot better when I'm hungover. I feel like I unlock a key of words that I don't usually use in day-to-day life.”

“I found out that I'd broken up with someone when I wasn't even aware I was going out with them!”

“I learned a lot from Rudimental's live set. It's all about good feelings, good vibes and a good time, and that's what I want from my shows. I like big, bolshy performances, like Beyonce. I can't dance like her, though.”

“I like Aveda shampoo. I've used it since I was a swimmer.”

“I love fierce performers.”

“I love sushi. Once on Valentine's Day, someone I was dating rocked up at the airport to pick me up with a bag of salmon because I love it so much.”

“I take up my make-up with Garnier's Micellar and then exfoliate with a Kiehl's exfoliating cream.”

“I think for us up-and-coming artists, once you're out there, once you've put stuff up, once people know who you are, once you discover who you are, we're all in the same boat: it's down to whether people appreciate the music or not.”

“I wake up every morning, and life is different. I've got a gig or a shoot. Flying here, flying there. Meeting wicked people. Going to amazing places. I'm relishing it.”

“I was a competitive swimmer as a teenager, only stopping when I got persistent ear infections. Every day was a 6 A.M. start to swim before lessons, then choir or dance classes after.”

“I went to boarding school in Somerset and loved it so much that my teachers had to make me phone home when I first got there. Whenever I spoke to my mum, at the end of the call I would say, 'Love you, Mum', and she would say, 'Love you the most.'”

“I'd never been on tour until I met the Rudimental boys. Never done a live show in front of an audience.”

“I'm actually quite good at being friends with my exes. I'm friends with almost everyone. In fact, everyone! So I let them burn to a certain degree, and then I put out the fire for a while.”

“It's a small world. No matter what the circumstances, be nice to everyone, as you never know who you're going to see again.”

“I've always had loads of teddy bears.”

“My background was always more soulful pop. I was named after Ella Fitzgerald, and when I was a kid, I was listening to Lauryn Hill, Etta James, Joss Stone. For me, it was always about the voice.”

“My hairstylist uses the Bumble & Bumble hairspray, which is the best smelling hairspray there is!”

“My mum is very driven and has always kept me busy... She used to say to me, 'Nobody likes a teenager. So use your teenage years to work. Then enjoy your life when you're slightly older.'”

“My mum told me that grown-ups don't like teenagers, which is the last thing you want to hear when you are one yourself!”

“My mum's a bouncy, energetic, driven, crazy woman, and my dad's very relaxed, doesn't say much. I have the best of both worlds in my personality.”

“On a normal day, I crawl out of bed before 8 A.M., have a protein shake, chuck my gym kit on, and go for a class or personal-training session. When I'm back, I'll have poached eggs with salmon or spinach for breakfast before my stylists arrive to do my hair - which takes ages. I then go wherever I am needed.”

“People are always looking for something new and something to latch on to and to back something from an early stage.”

“There's a lot less time in the day when you're in a relationship.”
