‘Phoneographer’ Tiziana Vergari hates your brain and wants to do everything in her power to make it explode.
At least, that's we can only assume after she posted this brain-busting photo on Instagram last week.
The snap, featuring girls sitting down in a line, has sent the internet into meltdown as people try to work out just how many girls are in the shot.
Have a gander below:
What's your verdict? 8? 10? 12?
You couldn't be more wrong, chump.
Tiziana has confirmed in the comments that it’s actually just two sisters looking into a mirror. It was entered into Instagram’s Weekend Hashtag Project #WHPidentity, which asked community members to submit images celebrating individuality.
You win this round, Tiziana. You win this round.
