32. Niall Horan
If you were a fan of One Direction during the band's prime. You would know just how incredibly famous the boys were. They had a colossal following even during their X-Factor days, long before they had released any hit songs. Therefore, it's quite surprising to come across a selfie of Niall Horan on the Tube. Seemingly unnoticed by the general public.
It is no easy feat for a celebrity to take public transportation without being mobbed by crowds of fans. Especially when they're as well-known as Niall Horan. However, judging from the background of the selfie. It appears that nobody recognized him on that day. Horan must have been relieved to enjoy a peaceful ride on the Tube without any interruptions. Although it may seem like a small, insignificant moment. It is a reminder that celebrities are also regular people who occasionally prefer the anonymity. That public transportation provides.
