The pair also attended the Dior show together back in April.  

Naomi shares her two children, Alexander, 16, and Kai, with her ex-partner Liev Schreiber, from whom she separated in 2016 after 11 years together. 

Despite her break-up with Liev, the former couple have remained on friendly terms and are committed to co-parenting their two children.

In June last year, Naomi tied the knot with her partner Billy Crudup, 55, at a New York City courthouse.

She shared news of her marriage to Instagram posting a photo of the lovebirds as they posed on the steps of Manhattan courthouse shortly after tying the knot.

They wed for a second time in June and were supported by their children on the big day.

At the Balenciaga show, Naomi caught up with her good friend Nicole Kidman, 57, who looked incredible in a shimmering black gown. 

She was seen blowing kisses to the crowd. 

Also in attendance was Katy Perry who arrived wearing nothing under a fur coat. 

After sources hit back at speculation that Ozempic was the cause of Katy's trim new physique, the star showed off her jaw-dropping abs as she arrived for the show.

Katy teamed her look with distressed illusion boots that gave the impression of being matching tights, and oversized sunglasses.
