Poot Lovato: has the internet discovered Demi's secret sister?

How pop star's 'twin who was locked in a basement her whole life' captured the web's creatives and fans with onslaught of Poot memes and Photoshop efforts

In the best conspiracy theory to hit the internet ever (and that's not difficult, given that most of them are offensive in one way or another and involve terrorism), a Tumblr user has discovered the (possible) existence of pop star Demi Lovato's twin sister, Poot Lovato. Maybe.

On 3 October, a sketch of Demi Lovato was posted by Tumblr user Versaceslut, along with the photograph it was based on - a washed-out, overly lit fan photo, probably taken at a red carpet event.
