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.

The superstar belted out “I Will Survive” as models strutted down the runway—details about her iconic performance here.

The legendary musician blew everyone away with her surprise performance of “The Power of Love” and “I’m Alive.”
