Three wasn't a crowd this time!
All three were at Thomas van Straubenzee and Lady Melissa Percy's wedding, but this time around Kate Middleton was left at home probably because she had other things to do…
…like rest up to give birth to a future prince or princess!
The ceremony reportedly took place at St. Mary's Church with the reception following at Alnwick Castle, which is actually the castle that was Hogwarts in the Harry Potter films.
So yes, they basically had the most awesome wedding ever!
We don't know how hard the three might've partied it up later that night, but we wouldn't doubt Wills checked in with his expectant wife from time to time.
After all, there's no knowing just when she'll pop now!
Ch-ch-check out more pics from the wedding (below)!
