Celine Dion and J Lo take center stage in the 2024 Elie Saab fashion show.

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.

After her performance, Jennifer Lopez, Halle Berry and Camila Cabello came out to congratulate the stars … sharing hugs and cheek kisses as the models from the show applauded onstage.

Speaking of Lopez, she performed at the show too … one of her first since filing for divorce from Ben Affleck back in August.

Her performance starts with a few lines from Gloria Gaynor’s hit track “I Will Survive” … which definitely seems like a shot at her soon-to-be ex-husband.

The Elie Saab fashion show was titled “1001 Seasons of Elie Saab” … with more than 300 models each wearing unique looks for the brand formed in the Middle East.

Before the show, Elie Saab Jr. — the company’s CEO — promised to bridge the gap between fashion and entertainment with this show … and, between J Lo and Celine Dion, it seems they did just that.
