It’s not often that you see a fashion show with over 300 looks and accompanying performances by Celine Dion, Jennifer Lopez, and Camila Cabello, but last night, Elie Saab had lots to celebrate, as the designer marked the 45th anniversary of his eponymous brand.

Jennifer Lopez’s comeback to the stage was one of epic proportions. The singer, actress and producer, 55, was among the stars taking the catwalk by storm at the 1001 Seasons of Elie Saab event in Riyadh, Saudi Arabia, on Nov. 13.
