The ‘It’s Always Sunny in Philadelphia’ actor filed to legally change his name on June 26

Rob McElhenney’s kids are not big fans of their dad’s name change.

The It’s Always Sunny in Philadelphia star, 48, spoke with Variety last May before filing to legally change his name to Rob Mac, sharing that he was considering adjusting his moniker since his name is hard to pronounce.

At the time, McElhenney’s wife, actress Kaitlin Olson, 49, shared that the couple’s two kids — Axel, 14, and Leo, 13 — were not happy about the change. “The kids are really not happy about it, because they have that last name,” Olson said. “And so do I, legally!”

Rob McElhenney Files to Legally Change His Name Due to People Mispronouncing It — Here’s What He Wants People to Call Him

Kaitlin Olson Says She’s ‘Still Fighting’ with Husband Rob McElhenney After He ‘Went Rogue’ and Showed Their Kids in a Documentary

In June, McElhenney filed to legally change his name to Rob Mac, PEOPLE confirmed, shortly after revealing he was considering the move due to confusion over the pronunciation of his surname.

Entertainment Weekly reported that he will now be credited as Rob Mac in projects moving forward. Mac signed the documents in Los Angeles on June 26, per TMZ.

The actor has already been using his shortened name, and has been credited online as Rob Mac in FX’s official materials for the long-running sitcom, in which he executive produces, writes and plays the character of Mac.

Elsewhere in their interview with Variety, Olson revealed that she’s still mad at her husband for doing one thing that they agreed they wouldn’t do: show their children’s faces in public.

“We’d talked about not showing their faces,” Olson told the outlet. “I remember going through puberty — no kid should be seen publicly before they’re ready to. Everyone’s got their insecurities, and it’s not their fault that we chose this path and that we’re famous. Rob went rogue and put them in a f—— documentary! I’m still unhappy about that.”

“The kids love it,” McElhenney said, before continuing to share his thoughts on the subject. “I have a different perspective. Millions of people across the world say, ‘We love to watch them!’”

Olson retorted, “I don’t care about them — I care about my kids! We’re still fighting about it.”
