Catherine, Princess of Wales, has become a fixture at Britain's annual Trooping the Colour event, whether it's waving to adoring crowds or wrangling her son Prince Louis as he makes funny faces for all to see. But, after announcing she was undergoing treatment for an unspecified type of cancer, it's uncertain if the former Kate Middleton will be at the annual event after being out of the public eye for much of this year.
The royal family has not released an official update on Kate's condition since May 22, when a Kensington Palace aid told NBC News that she’s not yet returning to her royal duties. As of June 7, Kensington Palace had made no definitive statement about her participation in the June 15 Trooping the Colour parade.
