The Argentinian-born royal, 53, was spotted in a beautiful strapless Valentino gown which featured a tiered lace-adorned skirt with chiffon ruffle adornments and a figure-skimming cut.
The icy blue number was first worn by the stylish royal in 2011 when she was photographed alongside Prince Alois of Liechtenstein at a dinner following the religious wedding ceremony of Prince Albert and Princess Charlene of Monaco.
She was a picture-perfect royal in a diamond and aquamarine tiara on the wedding day and added a bejewelled belt to her dress.
