During a recent lunch at a ski resort in the French Alps, an observer witnessed William and Middleton sharing a very chummy lunch with her parents. Says the onlooker: “William was clearly very close to Kate’s father, and every time he spoke to him, William replied, ‘Yes, Dad.’ ”
So, when will an engagement happen?
Oddsmakers are wagering 1 to 2 that Prince William will pop the question soon. “We’ve seen quite a bit of money, suggesting an engagement is imminent,” says Nick Weinberg, a spokesman for the betting house Ladbrokes.
