We all know Instagram is all about making it look like you're living your best life - but one 'influencer' has been caught out - by her own family.
After Casey Sosnowski Instagrammed a photo of herself out for a hike in the woods - her sister Carly took to Twitter to call her out for lying.
"My sister said she was going hiking… this is our backyard."
Her post quickly went viral, getting over 273,000 likes and more than 40,000 retweets.
