When Is Kate Middleton Due? Duchess Less Than 12 Weeks Pregnant With Second Royal Baby: Report

A second royal baby is on the way for Britain's Duke and Duchess of Cambridge, but it will be at least several months before the world gets a glimpse of the future monarch. Buckingham Palace confirmed Monday that the duchess Kate Middleton and husband Prince William, both 32, are officially expecting their second child, who will join the couple’s 13-month old son, Prince George, to expnad the royal family. The prince's grandmother, Queen Elizabeth II, and members of both families are reportedly “delighted” with the news, the Clarence House said in a statement.

So when is Kate Middleton due? With her recent bout of Hyperemesis Gravidarum, the acute morning sickness she suffered early in her pregnancy with George in 2012, it's likely that she is less than three months along. "She has not reached the 12-week stage yet," the Royalist is reporting. If Middleton is approaching the end of her first trimester of pregnancy, that means she would deliver in March or April 2015.

The royal couple’s second-pregnancy announcement follows closely in line with their first. In December 2012, after months of pregnancy speculation, the palace confirmed that the Duke and Duchess of Cambridge were parents-to-be. At the time, Middleton was reportedly less than 12 weeks along. Middleton was photographed shortly after that leaving King Edward VII Hospital in London after four days of treatment for acute morning sickness.

William and Kate, who have sparked numerous pregnancy rumors in recent months, were last reported to be expecting in mid-July. “Kate’s inner circle is buzzing with the news that she is expecting,” the Duchess’ longtime friend Jessica Hay revealed to Australia’s “New Day.” “I’ve heard from several different friends of their news that they’re saying that they think there’s going to be an official announcement in weeks.”
