Will Smith is shopping book

WILL Smith and “The Subtle Art of Not Giving a F--k” self-help author Mark Manson are collaborating on a book.

After a publishing source told Page Six about the project this past week, and we reached out to Smith’s rep for comment, the movie star announced the book in a video message.

“I’m writing a book! I got years and years of stuff I want to say, and I’m finally going to write a book for y’all,” Smith posted in an Instagram video with Manson.

Smith asked Manson in the video, “Are you feeling confident? Are you feeling like we’ll be able to do transcendent art with this book?”

Manson replied: “I spent the last six months with crippling anxiety, but today I feel great.”

Smith revealed that “We’re going to be meeting with five publishers . . . we’re gonna pick one. And if I had to take a guess, I feel very confident that we’re gonna go with the highest bidder ... I’m just saying.”

When we asked Smith’s reps about the project earlier, we were told that the star and the author “are meeting and talking, but nothing is locked.”

But Smith then publicly announced the project and revealed it is going out to publishers, and that the pair has been working on it for months. (Seems pretty “locked” to us?)

A source told Page Six of the project, “It’s supposedly going to be a memoir/inspirational book.”

Manson’s “The Subtle Art of Not Giving a F--k” has sold 3 million copies, and was a No. 1 bestseller.

Critics have called it “full of counterintuitive suggestions that often make great sense, is a pleasure to read and worthy of rereading. A good yardstick by which self-improvement books should be measured.”

Publishers should be lining up for his collaboration with Smith. Manson did not get back to us.

And though Smith has yet to write a book, the star has already inspired a number of motivational, independently published fan tomes by others with titles such as “Will Smith’s Rules for Success.”
