Anne Hathaway and director Garry Marshall are reuniting for the third installment of their beloved Princess Diaries franchise.

"I was with Anne Hathaway a couple weeks ago, it looks like we want to do Princess Diaries 3 in Manhattan," Marshall told People. "Anne Hathaway is very pregnant, so we have to wait until she has the baby and then I think we're going to do it."

The first Princess Diaries, in 2001, gave Hathaway her breakout film role. She played teenager Mia Thermopolis, heir to the throne of fictional Kingdom of Genovia, ruled by her grandmother Queen Dowager Clarisse Renaldi (Julie Andrews). The second installment, 2004's The Princess Diaries 2: Royal Engagement, helped launch the film career of Chris Pine, who played Hathaway's love interest, Lord Nicholas Devereaux.

Marshall noted the third film could feature Pine, who has since become a major star in films like J.J. Abrams' 2009 Star Trek reboot. "Maybe," Marshall says of the potential casting. "He's quite big now, you know."

The Princess Diaries 3 rumors have been swirling since last summer, with reports indicating that Debra Chase, one of the original film's producers, was set to work on the sequel. As Entertainment Weekly notes, a source close to Disney denied the reports at that time.
