The dark secret behind this Instagram star's beautiful photos.

Instagram feeds all over the world are filled with photos of women like Louise Delage. They sunbathe on exotic beaches, attend wild parties and somehow seem to fund it all without ever spending a day chained to a fluorescent-lit desk.

All the while we lie on our couches late at night, devouring their picture perfect lifestyles, desperately trying not to drop our smart phones on our faces.

In August, Parisian party girl Louise Delage appeared on the popular social media platform, with flawless complexion and annoyingly good hair.

Within just a few months the 25-year-old had more than 17,000 followers double-tapping her every move and a social media star was born.

She quickly racked up more than 50,000 likes with photos of extravagant dinners, cheeky bikini shots and boat parties; she almost always had a drink in her well-manicured hand.

But who was she? Noone seemed to know, or care.

Just over a week ago a YouTube video delivered the truth: Louise doesn’t exist — and far from being aspirational, her life was expertly designed to teach the world a harsh lesson about addiction.

Addict Aide are a French organisation focussed on raising awareness of alcoholism in young people.

With the help of a local production company, they created Delage’s persona in collaboration with the BETC ad agency, hoping to prove that a picturesque life can be used to distract from dangerous addiction.

“We were briefed on the difficulty of detecting the addiction of someone close to you—a friend, a child or a parent,” BETC creative director Stéphane Xiberras Paris told AdFreak.

“We thought an interesting way of showing it would be to create a person people would meet every day but whom we’d never suspect of being an addict, by setting up a fake Instagram account.”

Perhaps the most disturbing thing about the experiment is that it failed.

Building Delage's profile and following was the easy part, the difficulty was getting people to look beyond her filtered facade.

"We hoped for more followers to take notice of Louise's behaviour," Xiberras said.

"There were a few people who sensed the trap—a journalist among others, of course—but in the end, the majority just saw a pretty young girl of her time and not at all a kind of lonely girl, who is actually not at all that happy and with a serious alcohol problem.

"Sometimes it seems like in this era, the more people stage their ideal life on social media, the more that serves to hide a not-so-ideal reality."
