Demi Moore and Kate Moss proved that age is just a number as they rocked the catwalk during the Paris Fashion Week.

The "Ghost" actress surprised the audience as she joined a slew of supermodels and celebrities for the Fendi Spring 2021 couture collection.

Looking like a goth goddess on stage, the 58-year-old A-lister opened Kim Jones's debut, sporting a plunging off-the-shoulder silk suit, showing off her sexy decolletage.

Demi Moore and Scout Willis for Fendi

The "Charlie's Angels" actress was also seen slaying the runway with wide-leg trousers as she finishes the look with pulled-back hair while wearing statement chest-length earrings.

Aside from the brunette beauty, she also appeared with her daughter, Scout Willis. Just like her mom, the 29-year-old wowed everyone, donning an all-black ensemble with a longline coat, trousers, and boots.

This is not the first time that the award-winning actress debuted on the catwalk. Last November, "The Scarlet Letter" star made a cameo at Rihanna's Savage X Fenty lingerie fashion show.

Moore stunned the crowd with her sexy black lace leotard, wearing fishnet tights and layered jewelry. The mother-of-three went on dark, smokey eye makeup and deep berry lipstick.

Demi Moore's Fendi Look Sparks Surgery Rumors

Although the Hollywood star looked radiant on the runway, eagle-eyed fans can help but notice her heavily contoured cheekbones.

Over Twitter, fans are accusing Demi Moore of going under the knife and having botox or fillers.

"This is a drastic difference in the face. And I agree wholeheartedly with my previous statement in that she has cheek filler, a lip lift at the corners, and the stiffness of Botox," one wrote, alongside a side by side then and now photo.

Meanwhile, the second user echoed the same thought and tweeted, "#DemiMoore whoever did her surgery needs to lose their license. She was always beautiful and was aging gracefully. She didn't need surgery. I hope she gets a professional surgeon to fix her back as natural-looking as possible. She looks so different now...it's sad."
