Another celebrity children's book? Yeah, yeah, yeah.

Paul McCartney has become the latest washed-up celebrity to pen a children’s book, joining the likes of Madonna, Sarah Ferguson (the Duchess of York), Jamie Lee Curtis, and former supermodel Paulina Porizkova— all of whom used name recognition rather than literary talent to get published.

McCartney co-wrote High in the Clouds (surely not an ode to cannibis?) with author Philip Ardagh "who was brought in after a first draft to ‘finesse’ the book," reports the Associated Press. Translation: the first draft sucked and McCartney needed a hired gun to make him look good.

And how’s this for a downer of a premise: the alleged kiddie book is reportedly about a squirrel named Wirral whose mother is splatted by a tree knocked down by evil developers.

McCartney advises parents of "very little kids" to skip over the opening death scene, adding: "My little one (two-year-old daughter Beatrice) is too little. She likes the pictures though." And what's not to like about pictures of squirrel guts, we ask?

No word on whether the book includes a recipe for squirrel soup.
