The past thirteen years have flown by since The Princess Diaries 2: Royal Engagement was released, and fans of the Disney series have never given up hope on getting another sequel. And if new reports are to be believed, The Princess Diaries 3 is finally on the way. Will Anne Hathaway and Chris Pine return? Here's what we know so far.There's already a script:Author of The Princess Diaries book series, Meg Cabot told Entertainment Weekly that a script exists. She also said that if the movie gets made, it'll happen "kind of as a tribute" to Garry Marshall, director of the first two movies, who sadly passed away in 2016. But Cabot refused to reveal any further details, apart from saying that the movies would likely deviate from the book series. She said, "I think of them as two different universes."Garry Marshall was planning the third installment before he died:In an interview with People in March 2016, Marshall said, "I was with Anne Hathaway a couple weeks ago. It looks like we want to do The Princess Diaries 3 in Manhattan." Sadly, Marshall's plan never came to fruition, but it's possible that the sequel will still be set in New York, to honor his idea.Anne Hathaway has an idea for the sequel:Julie Andrews, who plays Queen Clarisse Renaldi in the movies, told Buzzfeed in February 2017, "Annie had an idea that she wanted to pursue about it, and I'm all for it, so if she'd like to…" And, yes, the "Annie" she's referring to is Anne Hathaway. Andrews also confirmed, "I would very willingly and happily do it."However, it might be some time before 'The Princess Diaries 3' comes out:Hathaway's rep reportedly told Buzzfeed in March 2017, "it's way too premature to discuss this project."Chris Pine is open to returning:In January 2016, during a fan Q & A for Entertainment Weekly, Pine was asked "Don't you pray every night for a Princess Diaries 3?" And of course he replied, "Have you been reading my diary???"Mandy Moore would consider a cameo:In July 2017, Moore told ELLE.com, "If I'm going to be involved, I would be down for a cameo—maybe she could make amends with Mia and apologize for being a bully when she was younger. She was insecure, going through a difficult time in her life and reflected on why that wasn't okay."Princess Mia's best friend, Lilly Moscovitz, would come backIn July 2016, Heather Matarazzo, who played Princess Mia's best friend Lilly Moscovitz, told Cosmopolitan that she would definitely return for another sequel. She said, "If Annie and Julie are down, of course."The Fans Are ReadyWhile fans are still waiting on an official announcement, there's plenty of time to rewatch the first two movies to fall back in love with the Princess of Genovia.
