Fans of Mia Thermopolis and, of course, Fat Louis, can now rejoice. After six long years, A Royal Wedding, the next book in the Princess Diaries series is set to be released on June 2. The story follows the now 26-year-old royal’s upcoming marriage with her high school sweetheart Michael Moscovitz, which we all remember was played by cutie Robert Schwartzman in the first The Princess Diaries movie.

In an interview with Cosmopolitan.com, author Meg Cabot says, however, that A Royal Wedding is decidedly more grown-up. It won't be anything like Fifty Shades of Grey, Cabot says, but there will be sexual references.
