Princess Anne was joined by fellow royal Olympian Prince Albert of Monaco as the pair attended a Rugby World Cup match in Paris, France on Saturday.
The Princess Royal, 73, was seated in the row in front of the Monaco head of state, as she supported Scotland's rugby team.
Sadly, there was disappointment for Anne as Scotland were beaten by Ireland 36-14, earning themselves a place in the quarterfinals, where they will face New Zealand on Saturday 14 October.
Meanwhile, Prince Albert, 65, is a huge rugby fan, and has attended several matches since the tournament began on 8 September.
Princess Charlene, 45, also joined her husband at the South Africa and Scotland match in Marseille last month.
Sport is something which Albert and Anne both have in common.
The Princess Royal was the first member of the British royal family to compete in the Olympics, when she rode the Queen's horse, Goodwill, in the equestrian three-day event at the 1976 Montreal Games.

And of course, Princess Charlene (nee Wittstock) represented South Africa at the 2000 Sydney Games, with her team finishing fifth in the 4 x 100-metre medley relay.

The Princess Royal's daughter, Zara Tindall, won a silver medal as part of Great Britain's eventing team at the London 2012 Olympics. Anne proudly presented Zara with her medal during the presentation ceremony.
