Like mother, like son!
The date of their baby announcement is extra special since his late mother Princess Diana officially announced she was expecting her second child — Harry — in February 1984. Although the Palace made the announcement on Feb. 13, it was splashed across newspapers on Valentine's Day.
According to an archived Daily Express newspaper from the time, Diana's pregnancy was made public in a statement from Buckingham palace that said Queen Elizabeth and Prince Philip were "delighted" by the news, adding that Diana, who was then 22, had "no preference whether it is a boy or girl."

One headline said it would be "Double the Fun and Double the Mischief" alongside a photo of Prince William, who was 20 months old at the time of the announcement. Diana and Prince Charles welcomed second son Harry on Sept. 15, 1984.

The happy news comes after Meghan revealed she suffered a miscarriage last July. "Losing a child means carrying an almost unbearable grief, experienced by many but talked about by few," she wrote in a searingly honest and heartbreaking New York Times essay on Nov. 25.
A long-awaited statue to honor Diana is set to be installed on July 1, what would have been her 60th birthday. William, 38, and Harry issued a rare joint statement last August announcing that the statue will stand in the garden of their mother's former home, Kensington Palace, and help people "reflect on her life and legacy."
