Teamwork makes the dream work—or at least that seems to be the case when it comes to British royal family members Prince William and Kate Middleton. The duo were out and about for a historic event today, and throughout the proceedings, they remained a united front.

The historic moment in question? Today marked the first time in 17 years that France has made an official State Visit to the U.K. This meant the arrival of French President Emmanuel Macron and his wife, Brigitte Macron. And Princess Catherine, Prince William, King Charles and Queen Camilla were all on hand to greet them.
