Stunning official photos of the Luxembourg royal couple and their wedding guests

Europe's latest royal wedding saw it welcome a new princess and the Luxembourg royal family gain a new member.

And the joyus occasion was a true family affair, with groom Prince Guillaume's sister as one of Stephanie's maids of honour and his nephew take on the role of page boy.

The family, who reside in Luxembourg's Grand Ducal Palace, is headed by 57-year-old Grand Duke Henri and his Cuban-born wife Maria Teresa.

Their 30-year marriage has given the couple five children, Guillaume, 30, Felix, 28, Louis, 26, Alexandra, 21 and Sebastien, 20, as well as two grandchildren Gabriel, 6 and Noah, 5, by Prince Louis and his wife Tessy.

Guillaume, who was Europe's last heir to tie the knot, married Stephanie in a ceremony that attracted royals from around the world and helped put the tiny landlocked country on the map.
