Grace Kelly's granddaughter, Charlotte Casiraghi, marries her fiancé as a film producer during a civil ceremony

Grace Kelly's granddaughter, Charlotte Casiraghi, and her fiancé as a film producer got together in Monaco.

Unlike the funeral of the American actress, which was attended by hundreds of people, including Princess Diana, in 1982, Charlotte, 32, engaged in a very discreet affair with a small civil ceremony followed by a party in the garden.

Her new husband, 37-year-old Dimitri Rbadam, was even thrown into a swimming pool in the well-fitting costume that he wore for the big day.

A photo of the happy couple, where Charlotte wore a long-sleeved dress from Diambattista Valli, announced their wedding with the legend "just married!"

The discreet royal wedding: Shortly after his wedding, the groom, still wearing his wedding suit, was thrown into a pool by friends.

For her wedding, the bride wore a long-sleeved mini-dress with floral details and three huge knots. His hair was styled by John Nollet.

The groom, meanwhile, donned a tight fitting navy blue silk suit with a wedding clutch at Monaco's Ingrimaldia Palace, where Grace Kelly also married in 1956.

The couple has a seven month old son named Balthazar.

After the small ceremony, the Instagram images seen by MailOnline show that guests were allowed to relax by the pool and on the air of the group inspired by the 1970s, Alessandro Ristori and the Portofinos.

A hilarious video also shows that Dimitri is thrown into a pool by guests. He dodges a giant inflatable watermelon closely.

Other pictures show guests laughing and sipping drinks in a sunny garden.

Princess Caroline of Hanover, mother of Charlotte, accompanied by her brother Andrea and his wife Tatiana Santo Domingo, also attended the ceremony.

According to People, Prince Albert II, Charlotte's uncle, and his wife, Princess Charlene, were at the bride's side.

Dimitri's mother also came to the starry night alongside her half-brother Louis Giacobetti and her cousin producer, Thomas Langmann, winner of an Oscar.

The event differed markedly during the funeral of his royal grandmothers in 1982, where a video shows hundreds of people on the streets to say goodbye.

Members of the royal family are shown walking in procession behind the coffin parading through the streets of Monaco.

The American actress, who became royalty after marrying Prince Rainier III, a small European country, died after suffering a stroke and crashed in front of her car.

Charlotte, fashion icon, is known for her appearances in fashion week fashion shows, especially those involving Gucci and Saint Laurent.

Rbadam is the son of French actress Carole Bouquet and producer Pierre Rbadam.
