Monaco's Pierre Casiraghi tied the knot with his Italian fiancee Beatrice Borromeo in a lavish civil ceremony on 25 July. The pair, who married in the gardens of the Grimaldi palace, are set for an extravagant religious ceremony on 1 August in the bride's native Italy.

Hello! Magazine revealed the 29-year-old bride wore four different looks for the wedding celebrations throughout the weekend. For her civil ceremony to the 27-year-old son of Princess Caroline of Monaco, the journalist and TV presenter wore a pale pink ethereal gown by Italian label Valentino.

The fashion house shared a photo of the newly married couple on its Instagram, with the blushing bride looking lovingly into the eyes of her groom. Borromeo can be seen with tousled hair and a lilac floral headpiece.

"The House of Valentino is pleased to announce that Beatrice Borromeo wore a Valentino Haute Couture dress designed by Creative Directors, Maria Grazia Chiuri and Perpaolo Piccioli, for her civil wedding with Pierre Casiraghi on July 25th at the Prince's Palace of Monaco. The wedding gown was created in a pale pink and gold lace silk chiffon," the label captioned the first official photo of the couple.

According to Hello!, the bride then wore a "more relaxed rustic ensemble complete with white gloves."

For her third dress, Borromeo wore yet another Valentino for the wedding's evening party at the five-star Hôtel de Paris. The bride wore a floor-length gown with a bejeweled cloud pattern on the skirt. Hello! Magazine reported she opted for a high-necked sleeveless top instead of the plunging neckline feature on the dress during Paris Fashion Week.

Borromeo spiced things up for her final dress of the weekend with a turquoise and tropical fruit themed pattern gown by designer Marta Ferri. Ferri shared a photo of the newly wed bride and herself on Instagram.

The newlyweds are expected to have their religious ceremony on 1 August in the Barromean Islands. As previously reported, the young royal proposed to his bride-to-be with a pink diamond ring in 2014. The couple first met at university in Milan in 2008.
