Just a week after the Monégasque royals came together for the annual Love Ball the family were out to celebrate again, this time at the lavish Salle des Etoiles of Monte-Carlo's stunning Sporting Club.
Prince Albert's sister Prince Caroline, whose daughter Charlotte Casirgahi turned 27 on Saturday, chose a sequined navy and white lace dress for the event that is now in its 65th year.
French DJ Bob Sinclair provided the evening's music and joined singer Michael Bolton, TV presenter China Moses and Monaco's minister Michel Roger on the guest list.
A lot has happened for the Grimaldi family since 2012's Red Cross Ball with the arrival of Princess Caroline's first grandchild. The 56-year-old Princess became a grandmother on 22 March when her son Andrea and future-daughter-in-law Tatiana Santo Domingo welcomed their son Sacha into the world.
Built by Albert's father Prince Rainier III, The Sporting Club has hosted the gala ever since its foundation in 1948 which was presided over for many years by his consort, Princess Grace.
Following Princess Grace's death Albert's sisters Princesses Caroline and Princess Stephanie took up the mantle, often attending the ball with Caroline's children Charlotte, Andrea and Pierre Casirgahi. Unfortunately, this year only Caroline was able to make it.
