The Duchess of Cambridge, who announced her third pregnancy earlier in the month, will soon make her first public appearance.

Kensington Palace have confirmed that the much-loved royal will attend an event at Buckingham Palace on World Mental Health Day, 10th October. She will be joined by her husband Prince William and brother-in-law Prince Harry.

The event will celebrate those working in the mental health sectors across the UK and has already attracted an impressive array of guests -- among those, many from leading mental health organisations.

Kate, 35, has been forced to miss a number of events, including her son Prince George's first day at school, due to an acute form of morning sickness known as hyperemesis gravidarum - the same condition she battled while pregnant with their four-year-old George and two-year-old daughter, Charlotte.

Prince William recently opened up about the happy baby news, while also providing a quick health update on his wife of six years.

"It's very good news," he said at a National Mental Health and Policing Conference in Oxford, England. "We need Catherine to get over this first bit and then we can start celebrating. It's always a bit anxious to start with, but she's well."

He later added: “There’s not much sleep going on at the moment.”

"As with her previous two pregnancies, The Duchess is suffering from Hyperemesis Gravidarum. Her royal highness will no longer carry out her planned engagement at the Hornsey Road Children's Centre in London today."

It concluded: "The Duchess is being cared for at Kensington Palace."

Congratulations again to the soon-to-be family-of-five!
