From a stunning sister-in-law to stylish auntie Charlene, why the nuptials of Grace Kelly‘s granddaughter Charlotte will boast a glittering guest list to rival any royal wedding

Grace Kelly‘s granddaughter Charlotte Casiraghi and her film producer fiancé are set to have a glittering guest list when they tie the knot in Monaco tomorrow. 

Charlotte, 32, and Dimitri Rassam, 37, will marry in the state rooms of the stunning royal palace, according to , and are expected to welcome an array of blue-blooded attendees.  

The service, which is expected to be attended by royalty including the bride‘s mother, Princess Caroline of Hanover, will be followed by a private luncheon.

Charlotte’s two brothers and their wives – Andrea Casiraghi, 34, and his American socialite wife Tatiana Santo Domingo, 35, and Pierre Casiraghi, 31, and his model wife Beatrice Borromeo, 33, are also likely to make an appearance. 

Meanwhile her half sister Princess Alexandra of Hanover, 19, who Charlotte‘s mother Princess Caroline shares with third husband Prince Ernst August of Hanover, is also an expected attendee.

Meanwhile Charlotte‘s step-siblings, Prince Ernst‘s two sons from his first marriage – Ernst and Christian, along with their wives Russian fashion designer and filmmaker Ekaterina Malysheva, and Alessandra de Osma, a Peruvian former model and handbag designer, respectively, could also join the festivities. 

Charlotte attended the weddings of both brothers, who enjoyed a smaller ceremony followed by a more lavish one, in line with tradition. 

Charlotte‘s uncle Albert II, Prince of Monaco, 61, and his wife Princess Charlene of Monaco, 41, a Zimbabwean-South African former Olympic swimmer, are also likely to attend. 

Princess Stéphanie of Monaco, Charlotte‘s aunt and the youngest child of the Prince of Monaco – who is also a singer, could also make an appearance.  

The announcement of their wedding comes months after the couple were rumoured to have split. They later spoke out to dismiss the reports.

Charlotte and Dimitri will marry in a civil service in the spectacular Prince‘s Palace in Monaco. 

The bride-to-be‘s grandmother, Hollywood movie star Grace Kelly, married King Rainier III at the palace in 1956. 

It is thought Charlotte and Dimitri will take the opportunity to baptise their seven-month-old son Balthazar on the same day. 

There could also be a separate religious ceremony following the civil service, although this has not been confirmed. 

Previous reports suggested this could take place in Saint-Rémy-de-Provence, where Princess Caroline and her three children took refuge following the death of their father and her first husband, Italian businessman Stefano Casiraghi, in 1990. 

The couple will likely follow the lead of other Monegasque royals – including the bride‘s brothers, Andrea and Pierre – and hold a second, more lavish celebration to mark their nuptials at a later date. 

Rumours the couple had split started to swirl in January, with sources close to the couple telling Hola! their personalities were ‘incompatible‘. 

However Charlotte and Dimitri later released a statement dismissing the rumours.

They have since made a number of public appearances together, including to the annual Monaco Rose Ball in March and glitzy parties at the Cannes Film Festival this month. 

Charlotte, eleventh in line to the Monegasque throne, is the second child of Princess Caroline of Hanover and the late Italian businessman Stefano Casiraghi, who died in 1990. Her uncle, Prince Albert II, is the current monarch.

The mother-of-two reportedly met Dimitri in Paris shortly after the end of her relationship with Italian filmmaker Lamberto Sanfelice. 

The potential guest list for a larger celebration 

If Charlene takes the lead of other Monegasque royals – including the bride‘s brothers, Andrea and Pierre, she and Dimitri will hold a second, more lavish celebration to mark their nuptials at a later date. 

The guest list could include the likes of  Princess Eugenie and Princess Beatrice, who attended the nuptials of Charlene‘s stepbrother – Prince Christian von Hanover, when he married model Alessandra de Osma in 2017.

Christian and Alessandra wed in a low-key wedding at Chelsea and Westminster registry office, before jetting into Alessandra‘s native Peru for a second more lavish affair attended by Kate Moss and boyfriend Count Nikolai von Bismarck.

When they met, Dimitri already had a daughter with his ex-wife, Russian model Masha Novoselova, whom he divorced in 2016. 

Meanwhile Charlotte had a son Raphaël Elmaleh, now five, with Canadian-French-Moroccan stand-up comedian Gad Elmaleh, 48. 

Hola! reported the couple were engaged in early March 2018 before they confirmed the speculation with a glittering appearance at the Rose Ball – their first official event as a couple. 

They welcomed son Balthazar in October, making Princess Caroline a grandmother for the seventh time. 

The baby was the third new arrival for the Monaco royals in 2018. 

Charlotte‘s brother Andrea and his wife Tatiana Santo welcomed their third child Max Rainier in April, and just one month later Charlotte‘s brother Pierre Casiraghi and his wife Beatrice Borromeo welcomed their second child Francesco Carlo Albert. 

Who are Charlotte Casiraghi and Dimitri Rassam?

Charlotte Casiraghi is the second child of Princess Caroline of Hanover and the late Italian businessman Stefano Casiraghi, who died in 1990. 

She is eleventh in line to the Monegasque throne. Her grandmother was Princess Grace of Monaco and her uncle, Prince Albert II, is the current monarch.

Charlotte, 32, has a five-year-old son, Raphaël, with Moroccan-French stand-up comedian Gad Elmaleh, whom she dated from 2011 to 2015. She went on to date Italian filmmaker Lamberto Sanfelice, before splitting in 2016. 

Shortly afterwards she met fiance Dimitri Rassam, a 37-year-old French film producer. Rumours of a relationship first started swirling in early 2017.

Dimitri is the son of actress Carole Bouquet, a friend of Charlotte‘s mother, Princess Caroline of Hanover, and French Jean-Pierre Rassam, a French Lebanese film producer.

Jean-Pierre died from a drug overdose when Dimitri was just four years old. 

Dimitri has a daughter with his ex-wife, Russian model Masha Novoselova, whom he divorced in 2016. 

According to reports in Hola!, Dimitri and Charlotte first met in Paris before spending time together in her country residence in Barbizon, an hour outside the French capital.

The couple choose to keep a low-profile, although they did both attend the civil marriage ceremony of Charlotte‘s step-brother, Prince Christian of Hanover, and his wife, Alessandra de Osma, in London in November 2017.

News of Charlotte and Dimitri‘s engagement was first reported by Hola! in March 2018. The couple made their formal debut at the Rose Ball in Monte Carlo that same month.
