The British royals aren’t the only monarchy celebrating a love match this week after Prince Christian of Hanover wed his girlfriend Alessandra de Osma on Sunday.

De Osma, who first met Prince Christian in 2005 when she was just 14, dressed elegantly in a 1950s style cream tweed coat with textured sleeves. 

On her feet, she opted for a simple pair of nude suede pumps and carried a spray of delicate white flowers. 

Meanwhile, groom Prince Christian, who is the second son of Ernst of Hanover and Chantal Hochuli, wore a navy blue suit with pale blue shirt and a sky-blue tie. 

Hochuli, wearing a deep emerald frock coat, smiled as she threw a plume of rose petal confetti over the bride and groom.

The Prince’s step-brother Pierre Casiraghi the grandson of Grace Kelly, was in attendance with his wife, royal style icon Beatrice Borromeo, who later posted images of the union on her Instagram page.  

While the groom opted for a relaxed fit navy blue suit with pale blue shirt and a mid-blue tie, Alessandra finished her look with nude suede heels with strap detail around the ankle. She carried a spray of delicate white flowers in a simple bouquet
