Prince William and Kate Are Expecting Another Baby

It’s official: The Duchess of Cambridge is pregnant with her second child. A tweet posted Monday from the official account of the British monarchy confirmed that Kate Middleton, who married Prince William in 2011 and gave birth to their son Prince George in July 2013, is expecting another baby.

“The Duke and Duchess of Cambridge are very pleased to announce that The Duchess of Cambridge is expecting their second child,” the tweet said.

Royal officials told the Associated Press that the Duchess was being treated for severe morning sickness, and Prime Minister David Cameron said he was “delighted by the happy news.”

Since William is second in line to the British throne, this would make the upcoming addition to the royal family fourth in the order of succession.
