Royal Wedding Bells Ring in Monte Carlo!

On Saturday, Andrea Casiraghi, the son of Monaco's Princess Caroline and second in line to Monaco's throne, tied the knot with Tatiana Santo Domingo in a private Monte Carlo ceremony. Andrea — who is also Grace Kelly's grandson — first met Tatiana through his sister, Charlotte Casiraghi, when the pair went to school together in Paris. The newlyweds dated for eight years and welcomed a baby boy, Sacha, this past March.

Tatiana comes from a well-known family, too — she's the daughter of the late Julio Santo Domingo, once the second richest man in Columbia, and her aunt, Lauren Santo Domingo, is the cofounder of Moda Operandi and a Vogue contributor. Earlier this week, Lauren posted a picture of Tatiana's bachelorette party on Instagram, which showed a group of women on a yacht dressed in elegant white outfits with flower garlands in their hair. Congrats to the royal couple!
