The best reactions as Princess Catherine makes first public appearance in months - less than 24 hours after health update

Princess Catherine is back.

Less than 24 hours after the beloved 42-year-old Princess of Wales provided a long-awaited health update to her supporters, she appeared as part of Saturday's Trooping of the Colour celebrations in London.

The June 15 ceremony is an annual event performed on Horse Guards Parade in London by regiments of the Household Division. The ceremony is a celebration of the official birthday of the British sovereign. 

Princess Catherine - the honorary Colonel of the Irish Guards - sadly had to miss the rehearsal of the event back on June 8, but has delighted fans around the world with her appearance today.

Photos show the Princess of Wales alongside her husband, Prince William, and two eldest children - Princes George and Louis, and Princess Charlotte - as crowds cheered the royals as they made their way down The Mall near Buckingham Palace.

Princess Catherine was wearing a white Jenny Packham dress with black detailing and Irish Guards Regimental Brooch. She beamed a radiant smile to the crowd in her first Royal public appearance since Christmas Day.

The beloved princess could be seen talking to her children in the carriage before they arrived at Horse Guards Parade in Whitehall.

The Princess of Wales was absent from the dias, as she opted to watch the event from a balcony in the Duke of Wellington's former office with her three young children.
