Here's J.K. Rowling's Next Secret Project

The 'Harry Potter' author is making even more magic.

J.K. Rowling is one busy lady.

In addition to shelling out backstories and need-to-know deets on Pottermore, coming up with a "Harry Potter" follow-up play that's going to be so ridiculously epic it had to be "Deathly Hallow"-ed into two parts, she's also writing books under her screenname Robert Galbraith, and, of course, penning the screenplays for the new "Fantastic Beasts and Where to Find Them" movie series.

And guess what else, guys? She's also finding the time somewhere -- we suspect a little Hermione time-turner action might be in play here -- in her busy schedule to tap out another children's book right now. YEP.

In an interview with BBC Radio 2 on Monday (Nov. 2), Rowling revealed that she's been working on a new kids' story that she's really into right now, and while she doesn't know *exactly* when it'll be done, she's pretty confident it'll make way to our shelves at some point.

"I'm not going to give you an absolute date because things are busy enough, but I will definitely write more novels as J.K. Rowling," she said on the show. "I have so many ideas. I have written part of a children's book that I really love so there's will be another children's book and I have ideas for other adult books... I sometimes worry I'll die before I've written them all out. That's my mid-life crisis."

Also? Just in case you were curious if she was out there in the novel world under another pseudonym, J.K. confirmed that Robert is a one-time deal.

"Trying to run more than one pseudonym is a fool's game, I wish Robert had lasted longer because it was a lot of fun," she explained.
