While US funny man Zach Brff couldn't help tweeting a little quip, saying: "UK, congrats on your royal baby. I think I saw some pictures of the day of conception."

Oo er.

Heck, even Voldermort has had his say, tweeting: "#royalbaby is trending. So soon there will be a new half-blood Prince?"

Plus, there is already loads of chat about potential names for the baby with loads of people wondering whether the couple might name the baby Diana after William's late Mum.

There are already odds available on William Hill, with Frances being the bookies favourite.

Well, we suppose it is quite posh.

However, the bookies reckon it's unlikely the baby will be called Peaches which is at 500/1 or Brooklyn, the name of David and Victoria's Beckham's first born, which is at 1000/1.

However, they also thought Christopher Maloney would leave X Factor in the first week so frankly, what do they know?

And the #royalbaby hysteria shows no sign of slowing.

You can even put your money on what colour hair the baby will have, with brown being the favourite.

In case you are interested, the odds are as follows: 6/4 Brown, 2/1 Blonde, 5/2 Black and 8/1 that he or she is a ginger.

Plus, the baby has already been named the most influential tot and that was before it was conceived.

This is one mega celeb we have on our hands, can you imagine the hysteria in six months time?
