'It's Always Sunny' Star Explains Name Change as a Gift to Fans: 'Minutes of Your Life Stolen by Me because of My Last Name'
- Rob McElhenney, star and creator of It's Always Sunny in Philadelphia, legally shortened his name to Rob Mac in early July 2025 in Los Angeles.
- He changed his last name due to frequent mispronunciations and misspellings of McElhenney and to simplify interactions as he is widely called Rob Mac already.
- McElhenney explained the change with a video featuring a 60-second timer and examples of his many ancestral name spellings, emphasizing family support despite his wife Kaitlin Olson and children retaining the original surname.
- He explained that he has spent countless days correcting others on how to pronounce or spell his name and referred to well-known performers who adopted stage names to support his choice.
- The official name change suggests a practical move to reduce confusion, while McElhenney encouraged fans to focus on broader issues beyond his reidentification and confirmed the name Rob Mac is here to stay.
