This is model behavior.

Irina Shayk heated up the 2023 Cannes Film Festival as she walked the red carpet for the premiere of “Firebrand” yesterday, wearing a barely-there bra top and matching leather maxi skirt.

The model, 37, sported a look from Mowalola’s fall/winter 2023 ready-to-wear collection consisting of a crisscross, bandage-style black top with red accents and a super low-rise skirt with a zipper at the top.

She wore her brunette hair in a simple, straight style and went with a minimal makeup look, accessorizing with just a stunning diamond Messika necklace.

The Akh-Ba-Ka necklace features diamonds cut from a single rough stone and it’s centerpiece is a whopping 33-carat cushion diamond.

Social media users didn’t seem to get the look, like one fan who commented on Check the Tag’s Instagram post writing, “I’ve never seen a greater wrong in Cannes.”

“She’s gorgeous, her body is undeniably banging and this is a super cool look but for anywhere else besides Cannes…like the VMAs or Grammys or the designer’s fashion week show…but for Cannes I think it’s a bit too conceptual,” another added.

Shayk — who hung out with Leonardo DiCaprio at Coachella this spring — is no stranger to a bold look, with Bradley Cooper’s ex sporting a pantsless outfit at a Formula 1 race earlier this month.

For more Page Six Style …

She also broke one of Karl Lagerfeld’s biggest fashion rules by sporting sweatpants at a Met Gala afterparty this year following the Lagerfeld-themed bash.

As for her ex, Cooper, 48, the catwalk star was spotted speaking to him at the Met Gala after Page Six reported that the couple — who dated for four years and share a 6-year-old daughter, Lea — were  “trying to get pregnant” with a second child last fall.

“It was a real family getaway and they are considering getting back together. Irina would like her daughter to have a sibling,” a source shared after the two took a family vacation with Lea last summer.

Perhaps this sexy look might attract Cooper’s attention.
