The late Prince Philip reportedly gave his grandson, Prince Harry, a blunt caution about marrying an actress ahead of Harry’s 2018 wedding to Meghan Markle.

According to royal biographer Andrew Lownie, Philip told Harry after the couple became engaged in 2017, “One steps out with actresses, one doesn’t marry them.” Lownie includes the remark in his book “Entitled,” as reported by the Daily Mail.

Royal author Ingrid Seward also wrote in her 2024 book, “My Mother and I, Philip,” that Philip was “one of the very few wary” of Meghan when she began dating Harry in 2016. Philip — who died in April 2021 at age 99 — even compared Meghan to Wallis Simpson, the American divorcée for whom King Edward VIII abdicated the throne in 1937.

The marriage between the former Duke and Duchess of Windsor was considered scandalous at the time, especially because Simpson had been divorced twice. The couple stayed together until Edward’s death in 1972.

Representatives for Meghan, 44, and Buckingham Palace did not immediately respond to requests for comment.
