Simon Cowell is planning to write a children's book.

He said: "I have thought about it, and now I think I'll do it.

"It will be about animals... I've had to read a lot of these children's books and they're quite boring, I think I could do it better.

"I'm going to make a children's TV show as well, a music show for kids."

Simon admitted Eric will feature in the book, while there will also be a character based on himself.

He admitted: "Obviously sort of a hero figure."

But until the 'X Factor' star's new show materialises, Simon has been encouraging Eric to shun his favourite TV show, 'Dora the Explorer', in favour of movies which he himself likes, including 'Toy Story' and 'Shrek'.

Speaking to 'Extra' presenter Terri Seymour - who he previously dated - Simon said: "[Dora] has gone away on a really long holiday, unfortunately with that weird fox...

"We watched the 'Good Dinosaur' the other day, that was good."

While Eric is just two years old, Simon can already see a glittering sporting future for the youngster.

He said: "He could be an Olympic champion.

"We taught him how to swim, he really took to it well, and he does, he swims whole lengths."

Meanwhile, Simon has been having vitamin shots and drinking smoothies in a bid to stay youthful, and even tried a bizarre new drink recently.

He said: "It was something somebody recommended and even I went 'Christ this is a bit odd.'

"Caterpillars in tea. It's a caterpillar that lives in a mushroom... you put it and the mushroom in tea. Even I went, 'This is a bit too crazy.' "
