It's official: 'P.S. I Love You' is getting a sequel and Hilary Swank will return as Holly

Warning: Spoilers ahead.

The classic movie P.S. I Love You first premiered in movie theaters in 2007. That means it's been over a decade since Holly and Gerry's memorable love story stole all our hearts. We can thank Cecilia Ahern, the author of the book that the movie was based on, for that. Now, Ahern has published a sequel to the book, titled Postscript, as a follow-up to the original story. And what's even more exciting is that Hilary Swank, who played Holly in the movie, will be returning in order to reprise her role, Irish Central reports. While Mr. Dreamy, Gerard Butler, may not be back to play lovable Gerry, fans are definitely excited to see what goes down in the sequel.

Postscript released on September 19 in Ireland and in the United Kingdom. Unfortunately, readers in the United States will have to wait just a little bit longer, until April of next year, in order to read the highly-anticipated novel. According to author Ahern, the book takes place seven years after Gerry, Holly's husband, dies. She stated, "P.S. I Love You was from the perspective of the person who was grieving, the people who are left behind, and I wanted to tell the story from a new perspective, from the people who've been told they're terminally ill or they have life-altering conditions. Postscript is about a group of people who've been inspired by Holly's experience and they ask her to help them write their letters for their loved ones."

She also confirmed that the sequel will be turned into a movie - and used the opportunity to announce Swank's return. "There will be a Postscript movie," Ahern said. "One of the first people to email me when she heard the news was Hilary Swank. She was so excited, she wanted to read the book and she said 'I would love to support you in any way, shape or form'. Then she read the book and she said 'I want to make this movie.' It felt like a lovely reunion everyone back together again, now we don't have a director or a screenwriter or any of that, nothing's been announced yet, but the movie's happening! I'm delighted." And fans, like Ahern, are delighted too. Further details regarding the movie are expected shortly.
