The social media platform Instagram with more than 150 million active users who share daily more than 55 million photographs announced the most famous photo for this 2013. Oddly, the photo belongs to young Canadian singer Justin Bieber and was posted 4 months ago. The photo that received more than 1.5 million likes shows the young pop star alongside with the American actor Will Smith. Actually, this fact could be considered as quite expected since Bieber is the most famous user on Instagram with over 12 million followers.
