Prince Will and 20 close pals have celebrated the prince's final few weeks of singledom - and the press didn't catch a glimpse of it!
The secret bachelor party took place at a country estate in Norfolk, just two hours outside London.
The all-boys-bash was planned by best man Guy Pelly and younger brother Prince Harry.
So what about Kate's bachelorette party?
"Well, we know that's coming," said royal author Katie Nicholl. "I'm hearing possibly next weekend."
