Even Justin Bieber is hopping on the Conor McGregor bandwagon

If that Floyd Mayweather v Conor McGregor super fight ever happens, Justin Bieber will have a big decision to make.

In case McGregor's superstar status was ever in any doubt, recognition from perhaps the biggest pop star on planet Earth (sad, but probably true) should prove that the Notorious has become bigger than the sport.

During the UFC 196 main card, Justin Bieber uploaded a photo of the undisputed UFC featherweight champion which was met with a mixed reaction from the good people on social media.

Here's how the good people of Twitter responded to the news that Bieber had hopped on the McGregor bandwagon.

Justin bieber is with McGregor 😕💁
