Celebrities tell HELLO! their top beauty secrets

Whether they're walking the red carpet or strutting down a runway, some celebrities are always radiant everywhere they go.

Click through find out what beauty tips and secrets these gorgeous stars and royals, from actress Priyanka Chopra to Greece's Princess Olympia, shared with HELLO!.

Princess Olympia of Greece

The Greek Princess swears by Moroccanoil. "[I] have to put a lot of that in [my] hair because I dye my hair blonde so I have to keep it moisturised," she explained of her beauty tips.

She continued, "I'm obsessed with moisture... soft hair, soft skin, soft lips. And whenever I go away in the summer I always have to do my nails because they get damaged all the time in the sea."

Lily Aldridge

When it comes to beauty secrets, this Victoria's Secret Angel loves working out. "It's a great part of my day when I get to work out. It makes me feel good. It makes me feel ready for the beach," she said at the launch of Body By Victoria: The Easy Collection.

Lily added: "I think a great, fake tan is also great for the beach. It makes you makes you feel a little more comfortable in your bikini before you've gotten like a natural tan."

Elsa Hosk

"Sunscreen is really important," the Swedish beauty shared, while launching Victoria's Secret's new Easy Collection.

While sunblock is an essential, she admitted: "I think it's better to get a fake tan than fry in the sun and just drink a lot of water." 

Karolina Kurkova

"If you have a great skin you really don't need that much - Use a good cleanser. A good toner. Good milk cleansing cleanser at night because it’s very moisturising," she said. "Using a milk cleanser, like a creamy cleanser at night is really the key so when you sleep over night it’s not dry and your skin is nourished so when you wake up you have a nice dewy skin already and it’s all sunk in but it’s still there."

The legendary model added: "I always say having a positive good attitude and being happy from the inside out, it also shows. It's part of your beauty. That's something you really can't fake or buy. You really have to work on that, that you're always in a state that you're happy, you feel good and you're grateful, appreciative. It just shows being at peace with who you are and where you are in your life."

Hilaria Baldwin

"I do believe you are what you eat," actor Alec Baldwin's yoga guru wife confessed. "I'm addicted to feeling good. I try to think of the whole experience, not just putting the food in your mouth."

So, what does a typical day of meals look like for the yoga enthusiast? "For breakfast I'll have granola and hemp milk. Then I'll go a get a smoothie made with blueberries, mango, almond milk, peanut butter and kale," she revealed. "Then we'll have sandwiches for lunch with tempeh and for dinner a piece of fish with some vegetables or lentils."

Josephine Skriver

This Victoria's Secret Angel has the key to "baby soft" skin and any other beauty need. "I really use coconut oil for everything. I cook with it, I clean my makeup with it. I use it as a hair treatment. It’s a little bit of everything," she told HELLO! at the Keep a Child Alive Black Ball in NYC.

"That has been the secret. I learned in the industry how versatile that product is. That’s why every time I use any product I always make sure there is coconut oil in it. When you use the Victoria's Secret body product with coconut oil, you wake up with baby skin."

Stella Maxwell

This Victoria's Secret model knows how to stay cool for the summer with her beauty tricks. She said, "Drinking a lot of water, keeping hydrated, trying to sleep as much as I can and some sun. I think some Vitamin D is really important."

As for whether she prefers an actual or faux tan, Stella confessed at the VS Easy Collection launch, "A real tan if you can, if you're out in the sun, but obviously use a lot of sunscreen because it's not good for your skin."

Shay Mitchell

The Pretty Little Liar star admitted that when it comes to looking your best, it's important to be disciplined. "It's about having a regular routine," she said – which for her includes taking off makeup every night and swearing by weekly exfoliation.

The actress revealed she enjoys having mini-spa days at home – or even at work! "Bioré has these one-minute self-heating masks that I’m obsessed with,” she shared. "I bring them to set."

Shay also believes in staying active. "I love boxing. I like taking advantage of being outside in L.A. because the weather is so nice here."

Zoe McLellan

The NCIS: New Orleans actress, who also became a licensed aesthetician in 2011, dished on how to keep your skip tight and hydrated.

"I believe our skin is a reflection of our emotional state – people who are happy have a youthful glow," she said. "Also, we are what we eat! For hydrated/tight skin I suggest an avocado daily, cucumbers, salmon and water."

Meanwhile, some products she loves are Derma E hydrating mask and hydrating serum and Epicuren's Colostrum Cream.

Jasmine Tookes

The Victoria's Secret model shared her beauty must-have with us. "Oh, sunblock! You have to protect your skin." Jasmine also advised that, "It’s really important to stay hydrated."

Victoria Justice

The singer and Eye Candy actress likes to use a tinted moisturiser with SPF and has a whole collection of hats to keep the sun off her face. "I feel like that’s so important, to take care of your skin," she said.

As for her cosmetics fave, she recommends Posietint by Benefit – a versatile poppy pink lip and cheek color. "I’m really into that cause if you’re outside or in the water it still stains your lips," she enthused.

Priyanka Chopra

When it comes to her number one beauty rule, the Quantico star told us, "Moisturise, moisturise, moisturise! And [I'm] always washing my face before bed, no matter what."

Other secrets she revealed include using yoghurt on her skin and hair. "For my hair, I mix half a cup of yoghurt (for moisture) with 2 teaspoons of lemon juice (great for exfoliating), apply it to your scalp and leave it on for about half an hour. Shampoo as usual and voilà!"

Coco Rocha

"Stay out of the sun guys," the Canadian model said of her skincare tricks. "Drink lots of water and take time, a vacation of some sort. You don’t even have to go that far, but just give yourself a little break."
