Prince William and his wife, Duchess of Cambridge Kate Middleton, will be welcoming their third child in about six months.
Kensington Palace made the announcement on Twitter Tuesday.
The royal couple, who are already parents to 4-year-old Prince George and 2-year-old Princess Charlotte, revealed they were expecting for the third time on September 4.
“Their royal Highnesses The Duke and Duchess of Cambridge are very pleased to announce that The Duchess of Cambridge is expecting their third child,” Kensington Palace said in a statement at the time. “The Queen and members of both families are delighted with the news.”
Kensington Palace also declared Middleton was suffering from hyperemesis gravidarum, a severe form of morning sickness.
The 35-year-old was affected by the same medical condition during both of her previous pregnancies.
Middleton recently stirred headlines when she was spotted dancing with beloved children’s book character Paddington Bear Monday at a charity event.
