It's the day we thought we'd never see - Simon Cowell has become a father.
He made the announcement on Twitter, but fans were of course quick to joke about the birth.
This scary hairy baby picture from Parentdish did the rounds a lot.
Even Alan Sugar and Sinitta got in on the action.
While others couldn't help but joke about Simon's hairy chest.
But there were other ways of joking about the birth.
Particularly when it came to Cowell's trademark high-waisted trousers.
But it was mainly the name which seemed to tickle most people.
Some even struggled to quite believe it.
While some other observations were made.
But still expect to see this picture a lot.
