Prince William is flying solo (just for today).
The Duke of Cambridge headed to the wedding of his friends Melissa Percy and Thomas van Straubenzee at Alnwick Castle in Alnwick, England Saturday sans his pregnant wife Kate Middleton, who is on maternity leave.
And in what could've made for an awkward moment, Harry's ex-girlfriend Chelsy Davy was also there, serving as a bridesmaid in the wedding.
Princesses Beatrice and Eugenie also showed up to the royal affair, along with Middleton's sister Pippa, who sported a patterned peplum dress and matching hat.
Congrats to the newlyweds!
