Prince William was the best man at the wedding of his friend Thomas van Straubenzee over the weekend, but his wife Kate Middleton was a no-show.
The reason was obvious: Kate is due in a matter of weeks and did not want to risk going into labor early (a la Kim Kardashian) at such an occasion.
Prince Harry, as an usher, was there along with his girlfriend Cressida Bonas and Kate's sister Pippa Middleton, so Kate not coming was notable.
Because the nuptials took place at Alnwick Castle, a 300-mile drive from where Kate and William live, she decided to take it easy. Probably smart.
