Grace Kelly's Granddaughter Debuted Her Engagement Ring on the Red Carpet

Another day, another royal engagement! Grace Kelly's granddaughter, Charlotte Casiraghi (who is the eldest daughter of Princess Caroline of Monaco), is engaged to French film producer Dimitri Rassam after a year of dating.

Although the couple are yet to comment publicly on their engagement, Casiraghi seemingly confirmed the news on Saturday, when she stepped out for the 64th annual Rose Ball wearing a stunning diamond ring on her left hand. She attended the event alongside Rassam, in what People reports was their first official Monaco event together.

Casiraghi and Rassam started seeing each other in December 2016, confirming their relationship several months later, in March 2017. Per People, the couple got engaged three weeks ago while on a family ski trip in Austria; they are set to walk down the aisle in July. 

Congrats to the happy couple! Now, read on to see their red carpet outing (and a close-up of the stunning engagement ring.)
