Wow! Simon Cowell proved him and his 6-year-old son, Eric, are quite the dynamic father-son duo when he announced their plans to write a children’s book series called Wishfits together on Monday, February 24!

“To begin with, we have announced a seven-book deal with @hachettekids today,” Simon, 60, excitedly wrote. “WISHFIT is a world where the most unusual animals exist. The WISHFITS are magical, unusual and have evolved in a weird and wonderful way, combining two different species to form hybrid animals with very distinct characteristics!”

As the American Idol judge marveled over how “magical” it has been “to write a series of books” with his adorable mini-me, he gave some insight on their beloved book characters. “Some of Eric’s favorite WISHFITS include the DAT (dog/cat) the COG (cat/dog), the SNOG (snail/dog — the enthusiasm of a dog at the speed of a snail), the PEEP (pig/sheep), the CHUG (cheetah/slug — the slowest cat in the world),” he listed, noting the book will also feature “the HIPPOROO (hippo/kangaroo), the CHIMPANPOO (chimpanzee/poodle), the POLARBAT (polar bear/bat), the CROCOPUSS (crocodile/cat), the SHIGER (sheep/tiger — the most nervous cat in the world), the SPIKEY (spider/donkey) and many, many more.”

Simon — who shares Eric with longtime girlfriend Lauren Silverman and is also the proud stepdad of her 14-year-old son Adam — revealed the idea to write a children’s book “was inspired 3 years ago by a very special friend” who runs a Children’s Hospice charity.

“I told her one evening about some of the funny animals my son Eric and I would invent, starting with the Cog and the Dat,” the America’s Got Talent star explained. “And how every evening the two of us would think of the most unlikely animal we would like to have as a pet. She loved this idea so much she encouraged me to turn this into a book series.” It looks like the rest is history!

Although little Eric is still just a youngster, it seems his famous father is already preparing him to take over his Hollywood empire one day. In fact, Simon previously opened up about whether or not he pictures Eric following in his entertainment footsteps.

“He’s in training,” the music mogul adorably shared on U.K.’s This Morning in November 2018. “I’m getting him ready to do my job.”

We can’t wait to get our hands on a copy of Simon and Eric’s upcoming books!
