Kate's Harvard University speeches and William's Earthshot Prize ceremony were part of the couple's Boston trip.

Despite arriving during a royal race storm, the couple remained unaffected by palace activities in London.

William and Kate were spotted displaying PDAs on their Caribbean vacation just before their trip to Boston.

They met Boston Mayor Michelle Wu at City Hall and held hands at a Celtics game with William's hand on Kate's knee.

The Earthshot Prize ceremony was the highlight of their trip, where William even restrained Kate on the "green carpet."

A viral video showed William's affectionate touch towards his wife during the event.

Despite the controversy surrounding the royal family, William and Kate remained upbeat and positive throughout their visit.

The couple has been married for almost 12 years and has three children.

King Charles III's coronation on May 6th adds to the royal family's busy year.
