King Charles III

Kate Middleton attended the Trooping the Color parade Saturday in honor of King Charles III’s birthday. It was her first public appearance since her cancer diagnosis earlier this year.

Kate Middleton will miss the Trooping the Colour public rehearsal, but will she make a surprise balcony appearance?

The photograph shows King Charles III wearing his crown dressed in full royal regalia while holding Sovereign's Orb and Sovereign's Sceptre with Cross.

Top moments that stood out on social media included a red feather, a kiss, and, of course, the facial expressions of little Prince Louis.

King Charles III has been crowned at Westminster Abbey, the final mile of a seven-decade journey from heir to monarch.

Defense Secretary Ben Wallace said it would be “a spectacular and fitting tribute" to the monarch, who is also commander-in-chief of the U.K. armed forces.

Charles will be formally crowned on May 6 – a particularly important date for Prince Harry and Meghan as the day coincides with their son Archie's 4th birthday.

The palace says that rather than commission a new crown, as is customary, Camilla will modify Queen Mary’s crown using diamonds from Queen Elizabeth II’s personal collection.

"Christmas is a particularly poignant time for all of us who have lost loved ones," Charles said. "We feel their absence ... and remember them in each cherished tradition."

King Charles III will be crowned at Westminster Abbey on May 6 in a ceremony that will embrace the past but look to the modern world after the 70-year reign of the late Queen Elizabeth II.

In a sign of royal continuity, the picture of King Charles III is taken in front of a photo of his late parents, Elizabeth and Philip.

One industry expert has predicted a staggering 4.1 billion viewers could tune in to witness the queen’s funeral on Monday.

A surging tide of people — ranging from London retirees to former England soccer captain David Beckham — have lined up to file past Queen Elizabeth II's coffin as it lies in state at Parliament, so many that authorities had to call a temporary halt Friday.

Resurfaced photos of King Charles' swollen fingers have led some on the internet to either poke fun or express serious concern.
