Demi Moore, 60, looks radiant in a demure black dress as she supports Salma Hayek’s brother’s new art opening at Christie’s in Beverly Hills

Demi Moore was among the stars who attended the grand opening of Salma Hayek’s brother Sami’s new Frequency art exhibition, now on view at Christie’s in Beverly Hills.

The 60-year-old Ghost star looked radiant for the occasion in an understated black dress with heels and a jacket she carried with her.

Demi and Salma, 57, are old friends and appeared to have a happy reunion as they chatted and posed for photos at the event.

Both the duo and the rest of the attendees took time to view the various works of art on display, including Sami’s latest acquisitions.

Frequency is described as ‘an exploration of the intimacy between materials and patterns as they intertwine. Sacred Geometry and the physical representation of Solfeggio sounds are deliberately blended to embrace the viewer,” according to the synopsis of the Christie’s website.

To complete her chic outfit, Demi carried a quirky black handbag and styled her raven braids into long, straight locks.

Along with Salma, Demi also posed for photos with other high-profile guests such as acclaimed actor Anthony Hopkins, actor and Evangelo Bousis, who is also the co-founder of luxury brand Dundas and fellow fashion designer Peter Dundas.

Like Demi, Salma looked youthful in her stylish ensemble which consisted of a mix of a silver skirt with a sleeveless black top and silver platform heels.

The Frida actress, 57, would also wear her dark locks long, straight and flowing with a center parting.

She seemed undeniably proud of her brother’s achievement as they made their rounds together at the exhibition opening.

Sami, 51, looked sharp in black trousers with a matching sweater over a white shirt.

At one point, Sami and Moore walked side by side toward the camera, with their arms wrapped around each other.

‘I am honored to exhibit FREQUENCY at @christieslosangeles from November 3 to December 7. If you happen to be in Los Angeles, come check it out,” he shared in an Instagram post.

The one-time model has said he wants to create “simple, elegant, functional design works,” according to his bio Style Park.

For Hayek, it is more important to design an experience than an appearance or style: how an individual interacts with a design of their creation. His work is deeply influenced by the rich colors, flavors and luscious textures of his native Mexico.”

The artist is also ‘strongly involved in the design world as a whole.’ In addition to his studio, Hayek has held several prestigious positions in the design world, as a lecturer, critic and lecturer in international design.

Sami has designed high-end residential and commercial interiors in Los Angeles, Mexico and Turkey. As well as residential and commercial buildings in Mexico and the US.”
