Princess Diana knew she was expecting a boy during her 1984 pregnancy in Britain but withheld that information from Charles, royal biographer Ingrid Seward claims. Her account revisits Diana's recollections that the then-Prince of Wales wanted a daughter and did not know Harry's sex before his birth.
For context, Buckingham Palace announced Diana's second pregnancy in February 1984, following Prince William's birth in 1982. According to Seward's account, Diana knew the baby's sex from a scan but chose not to tell Charles because she understood his preference.
