Demi Moore made a surprise appearance at Haute Couture Fashion Week in Paris by opening Fendi's Spring-Summer 2021 show.

Wearing an off-the-shoulder jacket with matching trousers and long, geometric earrings designed by Kim Jones, Moore opened the show and was later joined by supermodels Naomi Campbell, Cara Delevingne, and Christy Turlington.

The show also featured appearances by Kate Moss and her 18-year-old daughter Lila.

Last fall, Moore, 58, appeared during Rihanna's Savage X Fenty fashion show, though her Fendi appearance marks her runway debut.

The Ghost actress had worked with Jones, who is Fendi's artistic director, before; she posed for a book of portraits in 2019 wearing Jones's designs.

"Thank you to the wonderful cast that made this happen true friends and family," designer Jones wrote on Instagram following the show. “I love you all !”
