Strong genes aren't the only thing that Princess Diana inherited from her grandmother.
Eight months after her brother, Charles Spencer, posted a charcoal sketch of Cynthia Spencer, who looked like a carbon copy of the Princess of Wales, the 57-year-old writer shared a vintage snap of their grandmother, and it's hard to miss the infamous head tilt—one of Diana's most popular go-to poses. Spencer wrote in the caption, "My grandparents enjoying their tea ‘al fresco’ at Althorp, in 1944. Photograph taken by my father whilst on leave from military training."
