Apparently David Walliams loves teasing Simon Cowell so much that he wrote a book. David’s latest is all about Simon’s son, Eric. He apparently gave Simon fifty copies of the book, David Walliams presents Baby Eric, backstage at Britain’s Got Talent.

The cover is an illustration of Simon and girlfriend Lauren Silverman with their son.

The blurb reads: “Simon Cowell was the man who thought he had everything, until the day Baby Eric arrived in his life. This is the story of how Eric David Sinitta Louis-Walsh Cowell came into the world.”

A source told The Sun “He didn’t quite know what to say” at first but was then really touched. We wonder who Simon will give the other copies to?
