Even Kate Middleton doesn't know the royal baby's name yet

Yesterday Prince William welcomed Prince Harry to the sleep deprivation club, whilst out and about with Kate Middleton to launch the King's Cup regatta.

And whilst the world waits to find out what Baby Sussex looks like and what his name is, the Duchess seemed to confirm she didn't know it either.

She told reporters, 'As William said, we're looking forward to meeting him and finding out what his name's going to be, so it's really exciting for both of them and we wish them all the best. These next few weeks are always a bit daunting the first time round so we wish them all the best.'

Kate added, 'It's such a special time, obviously with Louis and Charlotte just having had their birthdays it's such a great time of year to have a baby, spring is in the air.'

Meanwhile, royal reporters have confirmed the royal baby will be presented to the world today, so hopefully not long to wait until we know the name.
