Conor McGregor dubbed 'The McGregor-Nator' by Arnold Schwarzenegger

Conor McGregor is quickly becoming one of the biggest stars on the entire UFC roster, and his win Sunday night over Dennis Siver sparked a whirlwind of attention for the Irish-born featherweight.

From start to finish, McGregor was in pure showman form as he took his sweet time walking to the cage to allow the Boston faithful to work themselves into a feeding frenzy.

McGregor's movements in the Octagon all have purpose, but the way he attacks always seems like he's putting on a show at the same time.

When he finally dusted off Siver in the second round and then leapt from the cage to confront featherweight champion Jose Aldo, it was pure theater and brilliant maneuvering for what will undoubtedly be the biggest fight the 145-pound division has ever seen.

Everyone took notice of McGregor on Sunday night including a couple of well-known celebrities. At the top of the list is former California governor and The Terminator himself, Arnold Schwarzenegger.

Considering the endorsement he just received, maybe McGregor can get some of that Terminator money that will be rolling in later this year when the new film opens up with Schwarzenegger starring? Or maybe McGregor could take a part in the sequel?

If Schwarzenegger's endorsement wasn't enough, the modern-day Terminator (at least in size and strength) also took notice of McGregor's win on Sunday.

"The Rock," also known as Dwayne Johnson, is a huge UFC fan, and apparently he's also joining the masses of McGregor supporters.

The star power surrounding McGregor continues to grow, and it's going to be fun to see what happens when he actually faces Aldo later this year in a pay-per-view with the title on the line.
