Britain’s Prince William and his wife Kate are expecting their third child, their office said on Monday after the Duchess was forced to cancel an engagement due to severe morning sickness.
The couple, who released the news via their office at Kensington Palace, did not say when the baby was due.
“The Queen and members of both families are delighted with the news,” the palace said.
Britain’s monarchy has ridden a wave of public support in recent years due to the emergence of the younger royals, William, Kate and William’s brother Harry.
Kate and William married in a lavish ceremony in 2011 watched by about two billion people around the world. Two years later the international camera crews and photographers camped outside a London hospital to record the birth of George, and returned two years later for his sister Charlotte.
George and Charlotte have since appeared on the front covers of magazines around the world and travelled on official royal tours of Poland and Germany with their parents.
“This is fantastic news,” British Prime Minister Theresa May said. “Many congratulations to the Duke and Duchess of Cambridge.”
William and Harry have been in the headlines in recent weeks as they led the efforts to remember their mother Princess Diana who died in a car crash in Paris 20 years ago last Thursday.
In a sign of how the young royals have helped to modernise the House of Windsor, the princes have spoken about the trauma of her death and its lasting emotional impact.
Kate last appeared with the princes on Wednesday when they visited a public garden at Kensington Palace dedicated to Diana but the palace said she would not attend an engagement at a children’s centre on Monday due to ill health.
“As with her previous two pregnancies, The Duchess is suffering from hyperemesis gravidarum….,” the palace said. “The Duchess is being cared for at Kensington Palace.”
Hyperemesis gravidarum can cause severe nausea and vomiting and requires supplementary hydration and nutrients. The condition led to Kate’s hospitalisation in the early months of pregnancy with her first child.
