While Kate has made a handful of appearances since announcing she had been diagnosed with an unspecified type of cancer earlier this year, including at the Trooping the Colour parade, the London Ballet, a church service in Scotland, and more recently, the Royal British Legion Festival of Remembrance, Tuesday's was one of the biggest engagements for the 42-year-old princess to take part in since overcoming some serious health issues.

King Charles III and Queen Camilla were also present for the grand welcoming, seen greeting their visitors separately from the prince and princess in a video uploaded to Instagram.

The Dec. 3 meeting comes just three months after Kate shared a pleasant update with fans on her improved health, announcing that after six months of chemotherapy treatments, she was finished and declared to be in remission.

According to the Daily Mail, she'll continue with today's other royal engagements, too, but will miss out on this evening's State Banquet.
