King Frederik had a warm reunion with the Duchess of Edinburgh at Wimbledon on Monday.
The Danish monarch, 57, was pictured greeting Sophie, 60, with a kiss as the Duchess arrived to take her seat in the royal box on Centre Court.
The royals spent a few moments catching-up in the VIP section, with Frederik appearing to react during one funny exchange.
