Ava Phillippe has a lesson for her fans. 

The daughter of Reese Witherspoon and Ryan Phillippe decided it was finally time to let her followers know how to pronounce her famous last name, and she knew exactly the way to do it.

Ava shared a screenshot of Lena Dunham's character Hannah Horvath from the show Girls to her Instagram Oct. 7, with Hannah explaining, "By the way, it's 'Phil-a-pee.' I heard it on Extra."

The 25-year-old added a heart hands emoji into the caption, writing, "#GIRLS."

And as was to be expected, many of Ava's followers were shocked to learn the actual pronunciation, with one commenting, "I thought it was fil-eep."

One fan couldn't believe it, saying, "lol wait…this whole time?"

And another joked that they weren't about to change how they were pronouncing it, writing, "Been saying ‘Phil lip hey' since 1999. Sticking with it haha."

Of course, there were some folks who were already saying it correctly, with one adding, "The pride I feel in this confirmation that I've been right since the 90s."

Another fan quipped, "If there's one thing I know, it's that it's PHIL A PEE."

No matter how you pronounce it, there's no doubt that Ava is proud of the moniker and has used her real name as her stage name while dabbling in the industry, mostly as model and influencer. And while some have alleged that she and brother Deacon, 20, have benefitted from being "nepo babies" thanks to their last name, their dad Ryan doesn't see it that way at all.

"That's what always annoys me about this whole nepotism talk with the industry," he told Extra in March. "So many people grow up and end up doing what their parents do, to some degree or another."

The 50-year-old added, "To me, I always get offended for the children of actors and entertainers when people bring that up because, of course, that's what they've grown up around."

As for Ava, she has not waded into the "nepo baby" debate and has instead focused on her own career—and making sure people know exactly how to say her name.
