Maybe it\u2019s a stunt and maybe it\u2019s not, but either way it\u2019s real: Rob McElhenney is changing his name to Rob Mac. The It\u2019s Always Sunny in Philadelphia<\/a> star filed the paperwork to legally change his name in late June and will be credited as Rob Mac in all projects from now on, per Entertainment Weekly<\/a>. Yes, he\u2019s 48. Yes, he\u2019s been going by Rob McElhenney on all projects since he began his career on a Law & Order episode titled \u201cThrill\u201d in 1997. But, hey, if a guy wants to change his name to something that sounds more like a McDonald\u2019s order than a name, he has the right to do so.<\/p>\n McElhenney\/Mac explained his decision in a video released July 1 on social media, saying that he just wanted to cut down the confusion over how to pronounce \u201cMcElhenney\u201d while also acknowledging that the name change is \u201ckind of douchey.\u201d \u201cThe amount of time that I have wasted trying to get people to either say or spell [my name] correctly is literally days of my life,\u201d he said in the video, adding, \u201cNot only have many generations changed the spelling, the current one was just given to my ancestor by a government official who decided that this was now the spelling.\u201d Plus, he claimed that \u201cmost people already call me Rob Mac anyway.\u201d Well, most people actually call him \u201cthat guy from It\u2019s Always Sunny,\u201d but that\u2019s neither here nor there. And, yes, the character he plays on It\u2019s Always Sunny is, in fact, named Mac (n\u00e9 \u201cFat Mac\u201d) \u2014 notably, It\u2019s Always Sunny\u2019s new season premieres on July 9. This whole thing couldn\u2019t just be a promo for that, right?<\/p>\n I said what I said. pic.twitter.com\/lvwKgTBBrx<\/a><\/p>\n \u2014 Rob McElhenney (@RMcElhenney) July 1, 2025<\/a><\/p><\/blockquote>\n McElhenney\/Mac first told the world about the name change in May, saying it was because of his newfound global business dealings with his company, More Better Industries, which recently purchased soccer teams in Mexico and Colombia. \u201cAs 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\u2019m just going by Rob Mac,\u201d he told Variety<\/a>. His wife and Always Sunny co-star, Kaitlin Olson, said the family wasn\u2019t thrilled: \u201cThe kids are really not happy about it, because they have that last name,\u201d she said in the interview. \u201cAnd so do I, legally!\u201d But the business deals in Colombia want what the business deals in Colombia want.<\/p>\n Related<\/p>\n \n
