Kepnes' bio originally said she was working on a third and fourth book, but added: "No, I'm not done yet."
However, she's now updated the section to say: "Yes, I finished writing the third Joe Goldberg book."
At a time when many projects have ground to a halt due to the pandemic, it's promising to see Kepnes has been keeping busy for us. Very good of her.
Kepnes also confirmed the exciting news on Twitter, responding to a fan asking if there was any update on the book.
"You3 is done and I know I keep saying 'soonish' but it's truly so done that I saw possible covers last week," she wrote.
"Your patience in a pandemic means the world to me. Thank you for waiting! Soonish he's yours.
Also spoiler alert. In You3 Joe bitches about the word 'soonish'."
And hopefully the third season over on Netflix shouldn't be too far behind, as that's also well underway - with the streaming service confirming just weeks after series two dropped that a third was also a goer.
A month later, executive producer Sera Gamble joined LADbible for an exclusive Ask Me Anything (AMA) on our Netflix Bangers Facebook group, where she answered your questions about the hit Netflix series.
Having been asked by one fan when the new season will be released, Gamble not only gave us a rough date for the third series' debut, but also gave us some insight to what to expect.
She replied: "We just opened the writers' room for season 3 of You.
"We're aiming for early 2021 but these things are always a little hard to pin down til we're close to ready. I will say: the new season is already BONKERS."
Gamble was also asked just how dark the show's sinister lead character Joe will go in season three.
Her answer was simple, and very, very ominous: "DARK."
Around a month ago, Gamble replied to someone on Instagram to say that the script for the third series was almost there.
She said: "It's mostly written. Now, to be able to shoot it."
Fingers crossed the team won't have to wait too long before they can get those cameras rolling.
