Prince William and his wife Kate are expecting their second baby, his office said in a statement on Monday.
“The Queen and members of both families are delighted with the news,” read a statement from Buckingham Palace.
According to the palace, the couple decided to announce the news because Kate, 32, is experiencing acute morning sickness and had to cancel a appearance at an event in Oxford scheduled for Monday. Her attendance at future events is also in doubt.
This condition had led to her hospitalization in the early months of pregnancy with her first child.
A spokeswoman said Kate had not needed hospital treatment this time, but was under the care of doctors at Kensington Palace, the couple’s London residence.
There was no detail of when the baby, which will be fourth-in-line to the British throne, was due.
The couple’s first child, Prince George, was born in July last year. George was born amid an international media frenzy, underlying the global popularity of the young British royals. Since his birth, George has graced the cover of Vanity Fair and his few public appearances have garnered huge media attention.
