Actress Lucy Hale could not pick me out of a line-up if her life depended on it, yet I could tell you more about her daily routine, thoughts and feelings than I could about my own sisters.

If pressed, I could easily tell you that her dog’s nickname is Elvie, she enjoys a Starbucks treat post gym visit and she currently has a very unfortunate scorpion infestation in her backyard that is in dire need of professional attention.

I don’t know these things because I choose to spend my Friday nights crouched in the bushes outside her bedroom window (frankly, that sounds uncomfortable and a waste of prime Netflix viewing time) or because I’m a super fan who has images of her placed atop a secret alter in my home.

All these facts have simply etched themselves into my brain because I, along with more than 21.5 million other people, follow Lucy on Instagram . She is a master of using the platform to tell her own stories, a prime example of how social media has given us more access to the the lives of celebrities than any paparazzi ever could.

Even if it is through a curated lens.

Opening up her daily life up to a legion of viewers has made the 29-year-old former Pretty Little Liars star one of the most beloved names on social media. However, there is a drastic downside to profiling yourself online and no one recognises that more than Lucy herself.

It’s an idea she had to face head on while filming her latest movie, the horror flickTruth Or Dare.

In the film her character Olivia goes from stoically using her immense social media following for good to using it in a way that, in the final moments of the film, will send an intense chill down your spine.

During the horror film, Olivia and her friends travel to Mexico where a stranger convinces them to play a seemingly harmless game of truth or dare. Once the game starts, it awakens a demon and then the rules become very simple, and very dangerous.

Tell the truth or die, do the dare or die, and if you stop playing, you die.

There are many actresses and actors out in the world with immense Instagram followings who will tell you they never read the thousands of comments that get left for them each day, but for Lucy it’s a very different story.

If you leave a negative comment on her Instagram account not only will she see it, she will also not hesitate to shut you down and send you on your way.

One of the downsides to Instagram fame, as anyone with a significant following can attest to, is that when you build up your story around the highlights of your life, you also find yourself having to publicly discuss the dark times as well.

Which is what Lucy was faced with this year when her TV seriesLife Sentence, her first solo starring TV vehicle and her highly anticipated follow-up to the juggernaut hit that wasPretty Little Liarswas canceled after one season.

Since she had covered the show's conception and journey so intently on her social media accounts, she then found her herself having to cover it's sad demise with equal depth.

So whether you're navigating the terrifying world of horror movies or the even more treacherous world of social media, keep Lucy's words in your head and remember that there is always a lesson to be learned.

Truth or Dare has now been digitally released across Australia. It is rated M.
