Kate Middleton, the Duchess of Cambridge, is pregnant again.
Kensington Palace released a statement on Monday morning, confirming that Middleton and husband Prince William are expecting their third child.
The duchess and Prince William are already parents to George, 4, and Charlotte, 2. The Queen — known to George as “Gan Gan” — is “delighted” with the news of the third pregnancy, Kensington Palace added.
According to the statement, the 35-year-old duchess is suffering from Hyperemesis Gravidarum — severe nausea and vomiting in pregnancy — and has cancelled a planned engagement in London on Monday. She suffered from the same sickness while pregnant with her first two children, ITV News reported.
It’s currently unclear how far along the duchess is in this pregnancy, but Peter Hunt, the BBC’s royal correspondent, said Kensington Palace had to announce the pregnancy earlier than planned because of “acute morning sickness.”
The news comes as George prepares for his first day at primary school at Thomas’s Battersea in south London. His parents were expected to accompany him to the door on Thursday, the Telegraph reported on Saturday, although it is unclear whether Kate will continue with this visit.
Prince William worked his last shift as a pilot for the East Anglian Air Ambulance this July, and transitioned to be a full-time royal as his 96-year-old grandfather, Prince Philip, retired from public service.
When born, the Cambridges’ third child will be fifth in line to the throne, bumping Prince Harry to sixth place, the Press Association’s Stephen Jones reported.

The royal couple joked about having more children this summer, when she told William “we will just have to have more babies” upon receiving a present for newborns in Poland, according to the Daily Mirror’s royal correspondent Victoria Murphy.
In July, an American company advocating for smaller families urged the Duke and Duchess of Cambridge not to have a third child out of environmental and health concerns.
“As you know and appreciate, the example the British Royal Family sets is extremely influential,” the Having Kids organisation wrote in an open letter. “Your discussion of having a larger family raises compelling issues of sustainability and equity.” These include flooding, heatwaves, increase in diseases, and wildlife extinctions, it added.
