Kensington Palace announced Monday that Princess Kate is expecting her third child with Prince William. The baby will join siblings Prince George, 4, and Princess Charlotte, 2.
"Their Royal Highnesses The Duke and Duchess of Cambridge are very pleased to announce that The Duchess of Cambridge is expecting their third child. The Queen and members of both families are delighted with the news." Kensington Palace said in a statement.
Kate has suffered from hyperemesis gravidarum, or acute morning sickness, with each of her pregnancies and the palace announced that she is again suffering from the disease.
Kate was forced to cancel a planned engagement this morning as a result of her sickness.
Unlike during her first pregnancy, where she was required to be treated at a hospital, Kate is being cared for at Kensington Palace.
Kensington Palace has not announced how far along Kate is in her pregnancy, but it is believed that she may be between eight and 12 weeks pregnant.
