E! News has reached out to Disney, as well as to reps for Anne and Julie, for comment but hasn’t heard back.
It’s clear that the movies, which are based on Meg Cabot‘s novel, have a special place in Anne’s heart. Last year, on the 20th anniversary, Anne gave a royal tribute the movies that made her a household name.
“Miracles happen,” she wrote on Instagram—referencing Myra’s hit track from the soundtrack—along with an array of photos from the film. “Happy 20th Birthday to #theprincessdiaries, AKA the film that launched a thousand sleep overs.”
News of the third film comes 18 years after the sequel, The Princess Diaries 2: Royal Engagement, was released in 2004.
