Prince William and his wife Kate, the Duchess of Cambridge, are expecting their third child, Kensington Palace has announced.
The announcement said the Queen and members of both families were “delighted” by the news.
Officials said the Duchess of Cambridge was suffering from Hyperemesis Gravidarum, a form of severe morning sickness, and would not carry out her engagements on Monday (local time).
The Duchess suffered from the sickness in her previous pregnancies and she is being cared for at Kensington Palace, the statement said.
William and Kate, both 35, already have two children: Prince George and Princess Charlotte, who are aged four and two respectively.
The royal announcement was a surprise, as there had been little indication that the Duchess of Cambridge was pregnant.
It also came at a time when the Royal couple is due to mark a milestone in the life of their young family: They are set to send George to school for the first time on Thursday.
No details were immediately available about when the third baby is due, but betting agencies were quick to start offering odds on possible names for the soon-to-be-born child in the House of Windsor.
Paddy Power was offering 10-to-1 odds on Alice, Arthur, Henry and Victoria.
Also popular was Diana, after Prince William’s mother, particularly given the announcement came shortly after the Royals marked the 20th anniversary of her death.
“Given the recent anniversary, there’ll be plenty of interest in the name Diana if the baby is a girl,” the agency said.
Last week the Royals toured the garden of their Kensington Palace home to remember the princes’ mother and celebrate her contributions to their family and to the monarchy.
Their third child would be fifth in line to the British throne and if the child is a boy, his arrival will be historic because he would not displace his big sister in the line of succession.
William is a grandson of the Queen and the eldest son of Prince Charles, who is the first in line to the throne.
