KENSINGTON Palace has revealed when the royal baby is due.
The Duchess of Cambridge is due to give birth in April, according to Kensington Palace.
The sex of the baby is not yet known to the public but it will be her third child.
Kensington Palace said William and Kate were "delighted" to confirm the month their third child is due to be born.
Kate has been suffering from hyperemesis gravidarum - a severe form of morning sickness - but made a surprise appearance at a royal engagement on Monday, and is due to visit Norway and Sweden with the Duke on an official visit early in 2018.
Her condition has improved in the last few days, allowing her to undertake two official royal engagements in the past week, but she is still not fully recovered.
It is understood that even if she is feeling much better by the time William goes to Finland next month, she has ruled out joining him there.
The condition, which made Kate ill in her first two pregnancies with Prince George and Princess Charlotte, can continue for the full nine months in some cases but often settles down in later stages.
The 35-year-old Duchess is already said to be feeling much better after making a surprise appearance at a royal engagement on Monday.
She took a twirl with Paddington Bear as they danced on the platform of Paddington Station, watched by William and Prince Harry, at an event for children supported by their charities.
