Power couple Beyoncé and JAY-Z added their star-studded presence to the second wedding of Tiffany & Co. executive Alexandre Arnault in the romantic city of Venice, Italy, on Saturday.

The 28-time Grammy-winning singer, 40, and her husband, 51, made a stylish entrance to celebrate the union of Arnault and his bride, Geralde Guyot. Arnault, the Executive Vice President of product and Communications at Tiffany & Co. is the son of Bernard Arnault, the CEO of LVMH Moët Hennessy Louis Vuitton. Meanwhile, Guyot is the founder of the French brand D’Estrëe.

Captured in photos, the music power couple looked absolutely glamorous. Beyoncé, adorned with a mask, dazzled in a blue dress paired with matching heels, a chic black coat, and a sparkling purse. Her neck was elegantly adorned with stunning jewels. Accompanying her, the 4:44 rapper looked sharp in a navy suit.

The Dreamgirls actress also shared glimpses of their time in Venice on her Instagram, treating her 213 million followers to a series of snapshots showcasing their lavish boat excursion on Friday. Beyoncé radiated sophistication in a one-shouldered, blue-and-white gown, while JAY-Z complemented her style in a black suit and sunglasses.
