They officially tied the knot five months ago in a small but stylish affair at Chelsea and Westminster Registry Office.

And now Prince Christian of Hanover and his radiant fashion designer bride, 25, said their "I dos" all over again - this time on a much more lavish scale.

A host of glamorous guests including several members of European royalty have decamped to the bride's native Peru, where the Prince and Alessandra kicked off a weekend of festivities with a cocktail party on the eve of the ceremony, reports Daily Mail.

Then came the main event, an extravagant chapel ceremony in celebration of their love. Princesses Beatrice and Eugenie made an appearance, as did supermodel Kate Moss who arrived alongside her boyfriend Count Nikolai Von Bismarck.

Kate Moss, 44, and Count Nikolai von Bismarck, 30, have been dating for more than two years.

However, it was reported late last year that she booted the handsome Count out of her home over his alleged refusal to tone down his wild partying ways.

He is reportedly close friends with Princess Beatrice and photographed her official 18th birthday portrait years ago. The Harrow-alumni even reportedly hiked the Inca Trail in Peru alongside Princess Beatrice on his gap year.

Kate and Nikolai took things public when they attended the launch of Kate's collaboration with fashion house Equipment and have been a public item since.

It was in Peru that the couple first met back in 2005, when a teenage Alessandra acted as Christian's tour guide.

It was for this reason that they returned in order to say their "I dos" all over again at the 16th Century Basilica San Pedro in Lima. The fashion designer wore a gown by Jorge Vazquez, which featured a high neck and an extravagant white train.

For the event she donned the Hanover Floral Tiara, previously worn by Princess Caroline of Monaco and her sister-in-law Ekaterina Malyshev. The groom wore a smart three-piece suit.

Kate Moss, 44, and boyfriend Count Nikolai Von Bismarck, 30, looked every inch the stylish pair as they arrived to the wedding.

Among the guests snapped attending Thursday night's pre-ceremony dinner were the groom's father Prince Ernst August of Hanover, his mother Chantal Hochuli, and Princess Jeanette zu Fürstenberg.

The glowing bride-to-be chose a £650 printed pink dress by cult label Borgo De Nor for the dinner on the eve of her big day, which she wore with vertiginous strappy heels in metallic pink.

Her dress for the ceremony itself will doubtless be a showstopper, given that she herself is a fashion designer.

At the civil ceremony back in November, the brunette beauty dazzled in a Chanel coat and heels by Aquazzura - not unlike the pair worn by Meghan Markle on the day her engagement to Prince Harry was announced.

According to local reports the ceremony will take place at Lima's Pedro de Osma Museum, a spectacular, century old building that exhibits Peruvian art dating back to the 5th Century.

The Basilica San Pedro, in Lima's historic centre, could also be the setting for the religious ceremony.

The celebrations are likely to carry on throughout the weekend, with lunch at the Club Nacional - where the great and good of Peruvian society and gathered for centuries - and cocktails at Casa Berckemeyer, an art gallery, believed to have been lined up for guests.

The couple announced their plans to marry in 2017 after dating for six years; they first met when De Osma was Christian's teenage tour guide on a visit to Peru in 2005.
