I hope you didn't get pregnant, Puzzled, it's amazing what a hug can do sometimes....
I'd never heard any rumours doubting Prince Andrew's parentage before this and am not sure I want to. It all seems ridiculous anyway, the Queen always loved her husband and they managed to stay the course. She wanted to have another child or two.
Andrew (certainly when younger) was better looking than his siblings in a more conventional good looking way but he's not unlike either parent or other members of the family. Looking at little prince George when he's serious, he's the image of Princess Diana's brother, Earl Spencer, but I'm pretty sure he is William's son.
Horrible nasty rumours. The Queen just would not, would have been far too risky.
