New photos show the Princess Royal and Ian Pattinson, R&A Chairman of the Board of Directors, looking on from the stands. The pair look on from the 1st tee during practice day four of The Open at the Old Course, St Andrews.
The Open Championship is the oldest golf tournament and will celebrate its 151st year on Thursday.
The tournament runs from Thursday to Sunday, with a prize pool of $14 million (£11,818,100).
The Princess Royal was made an honorary member of the Royal and Ancient Golf Club of St Andrews in February 2015, just five months after it decided to admit women.
