How many girls are actually in this photo?
The Internet is still arguing and guessing after this 'mind boggling' photograph was posted to Instagram last week.
Posted on Instagram by Swiss photographer Tiziana Vergari as part of an Instagram weekend hashtag project, the picture has gone viral and shared more than 12,800 times since it was posted a week ago.
The photo has attracted thousands of comments as people debate whether there is two, four, five and even 13 girls.
Some have even suggested they are twins or triplets.
'Girls #1 and #4 are different people. Look at how different their faces are!' one Instagram user wrote.
Another said: There's clearly four. Look at how the reflections are. If you see their face, the mirror shows the back of their head. If you see the back of the head, the mirror shows the face. The girls just look similar.
'There is 2 girls... the girls both have a mirror on the side of them which makes a replica of the mirrors making multiple picture of the girls,' another user wrote.
In amongst the thousands of comments, Ms Vergari actually confirmed there are only two girls in the photo and it's believed they are her daughters. Daily Mail added.
