In 2014, Princess Theodora made worldwide headlines after she stripped down at St Andrews University. The royal climbed a fence, stripped off and made racist remarks about 'killing Muslims' after attending an exclusive Oktoberfest party held at Kinkell Byre in the Scottish university town.
She was arrested and taken to court over the incident, and walked away with a £1,000 fine.
Guests at the wedding included Prince Maximilian zu Sayn-Wittgenstein-Berleburg and his wife Princess Franziska, Princess Katalin von Wrede and Princess Anna of Bavaria.
The princess's mother is Countess Yvonne Wachtmeister af Johannishus, who married Ludwig Ferdinand Prinz zu Sayn-Wittgenstein-Berleburg in Barbo, Sweden, in 1975.
Congratulations to the couple!
