The actor, who owns the soccer club Wrexham A.F.C. withRyan Reynolds, previouslyrevealed in an interview with Varietypublished in May that he was considering a name change.

Ryan Reynolds and Rob McElhenney:The duo lovingly spoof Wham!'s 'Last Christmas' single cover "As our business and our storytelling is expanding into other regions of the world and other languages in which my name is even harder to pronounce, I'm just going by Rob Mac," he told Variety. McElhenney, who plays Mac on "It's Always Sunny in Philadelphia," said in the interview that he was concerned about disrespecting his ancestors until he discovered there's a history of his relatives also tweaking the last name. "It turns out, as I did my genealogy and I got it back, my last name has been changed so many times," he said. "As late as the '60s, there were an offshoot of the McElhenneys that changed our name. And soit's not like everybody was so precious about it prior to 1965." But the actor's wife Kaitlin Olson told Variety that their two teenage sons aren't thrilled with the idea. "The kids are really not happy about it, because they have that last name," she said. "And so do I, legally!" The change comes more than two yearsafter Reynolds released a comedic songon McElhenney's birthday dedicated to teaching people how to say McElhenney, accompanied by a music video with clips of people butchering the pronunciation. "Sure, he's got a pretty face that people know they know," Reynolds sang. "They think they recognize him from his big-time TV show. But despite the accolades, despite the load of fame, one thing that they do not know is how to say his name."
