A thousand would-be princesses are weeping today, after News of the World broke this story.

One source close to the couple said: “William is the one doing all the chasing and he is the one saying he wants to make it work.”

Wills snogged Kate in the middle of a crowded dancefloor before taking her back to his room in the early hours.

The steamy encounter came during a party at Wills’ Army barracks earlier this month.

It was one of several intimate dates the couple have shared in recent weeks.

But Kate is not sure she wants to restart their romance. And if she does agree to go back to him full-time, she would demand total commitment from William.

A friend of Kate’s said: “It’s such a nightmare because she knows if they do get back together, there will be no turning back. There will have to be an engagement and then marriage.”

The party, at barracks in Bovington, Dorset, on June 7, was thrown for troop leaders including Wills to celebrate finishing a gruelling course.

Personally, I don’t really believe this. People seem to think they made a perfect couple, but when you’re part of the Royal Family you tend to keep the formal announcement to yourself until things are pretty definitely split up. Maybe it’s Tina Brown trying to drum up more interest in her new book, although with the upcoming Diana concert and 10 year tributes, it hardly seems like anyone needs a reminder that there’s a whole heap of books out about her life and death.
