Celine Dion and Jennifer Lopez are both getting back on the performing horse … taking the stage at a famous fashion show in Saudi Arabia Wednesday night. The singers performed during this year’s Elie Saab fashion show in Riyadh … providing the entertainment for the 45th anniversary gala — and, the 2 stars didn’t disappoint. First, Celine — who made her big return to performing at the Opening Ceremony of the 2024 Olympics in Paris — hopped onstage in a gorgeous golden gown, belting out hits like “The Power of Love,” “I’m Alive” and other classic tracks. Watch Dion’s body … she’s still dealing with Stiff-Person Syndrome obviously, but she’s moving around a bit here — strutting down the runway and telling the audience to get out of their seats.
