Fake or genuine aren't the only kinds of smiles; in fact, there are an estimated 50 types of smiles and we all do a number of them.
But there may be one kind of smile you have a tendency to favour and this is influenced by your astrological sign. Like our personalities, our behaviours are affected by our signs.
Here are your go-to smiles, according to your zodiac sign.
Aries (March 21 - April 19): The Synchronised Smile
Your smile, Aries, is a combination of a real and loving smile you give while leaning toward the person you're smiling about. Your smile says that you're excited and ready to take on your next adventure.
Taurus (April 20 - May 20): The Sad But Resilient Smile
Taurus, you feel every emotion deeply and it's difficult to hide whatever you're feeling. Your smile lets your friends know that although your heart has been broken, you'll be OK.
Gemini (May 21 - June 20): The Flirty Smile
The flirty smile is attractive and enigmatic, just like you, Gemini. Your smile makes people want to be with you and find out about you.
Cancer (June 21 - July 22): The Tight-Lipped Smile
Cancer people tend to follow their gut instincts and are often a bit guarded against the next emotional attack. Your smile can mean a lot of things including fear, shyness, politeness, reserve and hiding your true emotions.
Leo (July 23 - August 22): The Smirk Smile
One thing about Leos is that they know their own value, so their smile is somewhat self-satisfied and slightly arrogant with a dash of assh*le thrown in. The smirk smile is what you give to someone who failed that test you just aced.
Virgo (August 23 - September 22): The Polite Smile
Virgo, you tend to keep your emotions reined in, so you often have a polite but somewhat distant smile. This is the smile you give when you don't want to give away too much but don't want to seem like a jerk.
Libra (September 23 - October 22): The Naughty or Up-To-No-Good Smile
Libras are cheeky and charming, and often get caught doing something naughty. Luckily, their smile is completely disarming and helps them get away with all kinds of bad behaviour.
Scorpio (October 23 - November 21): The Open-Mouthed Smile
Scorpios enjoy a big and bold lifestyle, so why wouldn't their smile reflect that? Sometimes an open-mouthed smile can seem a little forced or fake, but with you it's just one of the ways you express your passion for living.
Sagittarius (November 22 - December 21): The Sparkle In The Eyes Smile
Every new place, new person or new challenge makes a Sagittarius happy. They have a lust for life that shows not only in their smile, but in their eyes as well. The term smiling eyes could have been created for Sagittarius.
Capricorn (December 22 - January 19): The Contented Smile
Capricorn, you wake up with a smile on your face and go to bed with one. You have a sense of peace about your life and your life's work.
Aquarius (January 20 - February 18): The Amused Smile
Sometimes you'll be walking by yourself and realise that you're smiling. You might be thinking of something funny someone recently said or you're just happy thinking about your own life. You don't care if you laugh out loud to yourself; you appreciate your unconventional ways of living in the world.
Pisces (February 19 - March 20): The Dazzling Smile
Pisces are super-creative and are always coming up with great ideas. When your genius strikes, you can't help but be pleased with yourself. Your happiness with yourself radiates off you, usually starting with a bright smile.
