MOMENT: Kate, Princess of Wales, joins royals on palace balcony

Kate, Britain's Princess of Wales, joined other members of the royal family on the balcony of Buckingham Palace on Saturday (June 15), concluding her first public outing since revealing a cancer diagnosis earlier this year. Kate, along with her husband William and their children George, Charlotte and Louis appeared on the famous balcony alongside the king, queen and other royals to watch a Royal Air Force fly-past in honour of the king's official birthday. Kate, 42, has undergone preventative chemotherapy since the cancer announcement, and while treatment is continuing, her improved health meant she was able to appear in public for the first time since last December.
