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.

Lopez kicked off her performance with a rendition of Gloria Gaynor’s “I Will Survive,” followed by her own version of “Waiting for Tonight.” With the second song, she dove from her floating stage into a sea of men in black tuxedos, who carried her onto the main stage. She also performed her hits “On The Floor” and “Let’s Get Loud.”
