The Queen made her return to the All England Club earlier this week, while Djokovic was gearing up for his semi-final clash with Jannik Sinner on Friday. The pair came face to face at SW19 last year before the Serbian star's quarter-final clash with Flavio Cobolli. The seven-time Wimbledon champion produced a dominant four-set victory on Centre Court. The match had been preceded by a meeting with the Queen, who made quite an impact on the tennis legend. Following his victory in front of the attending royal, Djokovic revealed he had been surprised by a question from the monarch but remained tight-lipped about what was discussed. "I prefer not sharing that. It's private," Djokovic said when questioned about his interaction with Camilla. "We had a nice exchange. I was actually surprised with her comment and a question that she asked. It was non-tennis related. She was very pleasant. Very, very pleasant. JOIN US ON FACEBOOK!

Wimbledon has traditionally attracted the Royal Family. It's beautiful to see there's still an interest in our sport. Of course, it's important for all of us."
