Charlotte Casiraghi has been pictured with her rumoured new beau after reportedly separating from her husband, Dimitri Rassam.
Paris Match published photographs of the Monaco royal enjoying the company of French writer, Nicolas Mathieu, in Paris earlier this month.
The author, 45, who has worked as a scriptwriter and news editor, won the coveted Prix Goncourt in 2018.
Model and equestrian Charlotte, 37, donned a smart-casual look in a navy coat, matching knitwear and blue jeans as she sat with Nicolas on the terrace of a café in the city.
Reports of Charlotte and Dimitri's split have been circulating in the European press for weeks, but there has been no confirmation from their representatives or the Monaco royal palace.
The pair were last publicly together at the 60th AMADE Anniversary Dinner at Monte Carlo Opera Garnier last October.

The pair married in June 2019, with a civil ceremony taking place in Prince's Palace of Monaco's Throne Room and later a religious celebration in Provence, France.
For the civil ceremony, the bride wore a brocade mini dress by Saint Laurent, complete with three dramatic bows down the front and a scalloped edge. She also wore her late grandmother Grace Kelly's Carter diamond necklace - a wedding gift from Prince Rainer when they married in 1956.
As well as Balthazer, Charlotte has a older son, Raphaël, born in 2013, from her previous relationship with Moroccan-Canadian comedian, Gad Elmaleh. Balthazar is 12th in the line of succession behind his mother, but Raphaël is not included as his parents never married.
