The lawyer, who was accompanied by her spouse George Clooney, was seen catching up with the likes of Christine Lagarde, George Osbourne and Joe Biden during the World Economic Forum in Davos.
The 38-year-old and her dapper husband, 55, looked to be having a great time with the managing director, 61, of the International Monetary Fund during the star-studded bash.
Wearing her tresses down in glamorous waves, Amal chose a stunning cream gown, which came complete with shimmery embellishment throughout.
The Beirut-born beauty made the most of her slender frame in the sleeveless creation, which featured a floaty skirt, grey waist and cropped detailing on the top.
