In a move we all saw coming, Rob McElhenney, star of the hit series "It's Always Sunny in Philadelphia," has officially filed to change his name to Rob Mac. His representative broke the news to Entertainment Weekly, confirming that this is how he'll be credited in future projects.

The reason behind this bold decision? McElhenney cited the global confusion surrounding the pronunciation of his last name, especially as his career expands internationally. "With our storytelling reaching various languages, my last name is a mouthful for many, so I'm opting for Rob Mac," he explained in a recent interview.

Rob Mac isn't just a name change—it's a brand! The actor has been making waves with his docuseries ''Welcome to Wrexham'', which chronicles the journey of the Wrexham AFC football (soccer) club that he and Ryan Reynolds acquired back in November 2020. His new venture sparked an investment in South American soccer clubs, where his original surname proved to be a comedic tongue twister.

In fact, Ryan Reynolds went all out to celebrate McElhenney’s birthday with a musical number dedicated to teaching fans the correct pronunciation of his last name. In a hilarious birthday video, Reynolds sang, "Pronouncing all those Ns, Es, and Hs can perplex 'em!" Clearly, even his friends realize the struggle is real!

Kaitlin Olson, McElhenney's wife and fellow "Sunny" cast member, chimed in about the family adjustment. "The kids are really not happy about it because they still have the last name! And so do I, legally!" Who knew a name change could stir such family drama?

Despite some initial reservations about changing a name that carries his family history, McElhenney discovered that some relatives had already tweaked the spelling or considered doing so themselves. It seems the pressure to simplify was a sign of the times.

Fans won’t have to wait long for the new credits—"Welcome to Wrexham" just wrapped its fourth season, which has already been renewed for a fifth, and season 18 of "It's Always Sunny" is still in the making. So get ready to see Rob Mac in all his glory!
