They are among the modelling industry’s most in-demand stars.
And Gigi Hadid and Irina Shayk both looked sensational as they walked the catwalk at the Max Mara fashion show for Milan Fashion Week on Tuesday.
Gigi, 26, looked stunning in a black bra top and mini skirt for the show while during the rehearsals she wore a yellow open shirt and leather trousers which highlighted her toned midriff.
The star also sported a matching pair of trousers while she added height to her frame with silver boots.
Styling her brunette locks into a ponytail, Gigi added to her outfit with a black handbag and a pair of sunglasses.
Accentuating her beauty with a light pallet of makeup, Gigi completed her look with a light blue headband.
The model was also spotted making her way to the rehearsal session where she donned a pair of black leopard print shoes and a cream face mask.

On Tuesday, Gigi gave fans a behind-the-scenes look at her baby Khai’s first birthday extravaganza on her Instagram Stories. She shares the tot with her former One Direction bandmember boyfriend Zayn Malik.

The balloon creations came in the form of a panda bear from the popular children’s animated show Word Party, which appeared to be the party’s dominant theme.
Some less impressive balloon displays, including a large number one to signify Khai’s first birthday, were scattered around the space.

Resting in the middle of the patio was a baby-safe enclosure that would allow the little one to hang out outdoors without getting into mischief.
The enclosure featured a small pale pink slide, an adorable hippo figurine, and blocks for Khai to play with as her guests mingled.
There was also a mini inflatable jumper with an attached ball pit for Khai to play in. ‘My baby turned one this weekend,’ captioned the runway maven on one of her posts.
