PHOTOS: Prince, Princess of Wales at Boston Celtics-Miami Heat

The royal pair were accompanied by Governor-elect Maura Healey, Boston Mayor Michelle Wu and others as they sat courtside to watch the game.

The Boston Celtics had some unexpected guests of honor in their home tilt against the Miami Heat on Wednesday night, with royalty of the non-figurative sort making a atop at TD Garden to take in a game from the hottest team in the NBA right now.

That would be the Prince and Princess of Wales, William and Kate, in town to promote the Earthshot Prize, awarded to five winners each year for their contributions to environmentalism and launched by William with renowned environmentalist David Attenborough. The royal pair were accompanied by Governor-elect Maura Healey, Boston Mayor Michelle Wu, and others as they sat courtside to watch the game.

Let’s take a look at the photos of the Celtics’ guests of honor for the evening.
