I have no internet buzz on this or scuttlebut I may have picked up at a royal do. I am working purely from the fact, established by the Royal Statisical Bureau that Minelli has porqd roughly one third of the male population of the planet. Given this statistic, odds are good that she has done both Phillip and Charles, but some confirmatory evidence perhaps from Lili or CG or Ichiban would be welcome given they are experts in the more prurient aspects of royalty.
