What better way to celebrate St. Patrick's Day than with a dose of the royal family? Prince William attended the Irish Guards's annual St. Patrick's Day parade in London today, and he was definitely in the festive spirit.

The Duke of Cambridge—who has the honorary title of Colonel of the Regiment—handed out shamrocks to the officers and servicemen and women at the Cavalry Barracks, and even presented their mascot Domhnall with his own sprig.

The Duchess of Cambridge was noticeably absent from the event, as her attendance at the celebration has become somewhat of a tradition over the past several years. "The Duchess has very much enjoyed the occasions when she has been able to attend, but the Duke is the Colonel of the Regiment and is looking forward to presenting the Irish Guards with their Shamrock," a Kensington Palace spokeswoman told People regarding her. "The Duchess looks forward to marking St Patrick's Day with the Irish Guards many times in the future."
