Yes — The Princess Diaries 3 is happening, but it’s still in development and does not have a confirmed release date yet.

Quick Scoop

  • Disney has officially put The Princess Diaries 3 into development as a continuation of Mia Thermopolis’ story, not a reboot.
  • Anne Hathaway is set to return as Mia and is also attached as a producer on the film.
  • Adele Lim (who worked on Raya and the Last Dragon and Joy Ride) is on board to direct, with a script by Flora Greeson.
  • As of early 2026, there is no official release date and no full confirmed cast list yet; Julie Andrews and Chris Pine have expressed openness in past interviews, but their return is not officially locked in.

What’s Confirmed vs. Rumors

  • Confirmed:
    • Disney and producers are developing Princess Diaries 3.
* Anne Hathaway has publicly celebrated the third film on social media with “Miracles happen” and “Back to Genovia,” signaling her return.
  • Not confirmed:
    • Exact plot details and timeline, beyond general comments that it will focus on themes like female power, joy, and mentorship.
* Viral “trailers” and fan posters circulating online; several outlets have warned that many of these are fan-made and not official marketing.

Latest News & Timeline Hints

  • The project gained real momentum in late 2024 when Hathaway and the creative team publicly acknowledged it and Disney’s involvement.
  • Reports suggest filming was being eyed for sometime after 2025, which makes a release before 2026 unlikely; it’s more realistic to expect news on filming before a solid release date.

Forum & Fan Buzz

Online, fans are treating Princess Diaries 3 as a nostalgic “comfort sequel,” sharing rewatches of the first two films and speculating whether Mia will be shown as a ruling queen and mother in Genovia.

Common wish‑list items in forum discussions include:

  • Julie Andrews’ involvement in some form (even a cameo).
  • The return of Chris Pine’s Nicholas, Lilly, and other original favorites.

In short: Yes , they’re making Princess Diaries 3 , but it’s still in the early phases the public can see, so keep an eye out for casting announcements and a real, studio‑released trailer rather than fan edits.
