#2 Leonardo DiCaprio
Leonardo DiCaprio is one of the greatest actors of the last two decades of cinema. He starred in a range of Oscar-winning movies before finally claiming his first-ever Academy Award in 2015 for his role in 'The Revenant'.
As one of the many celebrities who developed an interest in the UFC during the rise of 'The Notorious' Conor McGregor, DiCaprio has attended several events.

He was in attendance when Nate Diaz shocked the world by submitting McGregor with a rear-naked choke in his comeback win at UFC 196. DiCaprio was also in attendance when the Irishman faced his most heated rival, the undefeated Khabib Nurmagomedov at UFC 229.
In fact, 'The Eagle' almost landed on top of DiCaprio himself when he leapt out of the cage to attack Dillon Danis and the rest of his foe's team. The incident eventually led to the now retired Dagestani taking a picture with the famous actor.
#1 Donald Trump
Before he was the President of the United States, Donald Trump was a media personality who hosted 'The Apprentice' and even made several appearances in WWE, including at WrestleMania 23.
He is also known to have struck up a friendship with Dana White due to him having played a fundamental part in the MMA promotion's journey into what it has become today.
White credited Trump with helping save the UFC during its struggle for survival in the early and mid 2000s as the then Trump Taj Mahal was one of the few venues in which the promotion was allowed to host events.
Thus, almost two decades later when the UFC achieved mainstream sports appeal, Donald Trump attended UFC 244, which was headlined by Jorge Masvidal and Nate Diaz, as well as UFC 264, which was headlined by the trilogy bout between Dustin Poirier and Conor McGregor.
