If you needed confirmation that YouTubers are the modern-day equivalent of Hollywood stars, then you only need to look at the Sidemen.
A super-group of UK creators, they've worked together for more than 10 years and have a combined 130 million subscribers.
The seven members, most famously lead by rapper and boxer KSI, can't go anywhere without being mobbed by fans.
One of the group, TBJZL or Tobi Brown, says its "surreal".
Aside from KSI and TBJZL, the rest of the group is made up of Miniminter, Vikkstar123, Zerkaa, Behzinga and W2S.
