The Victoria’s Secret stunner opens her risqué film by Doug Inglish by galloping around on a pretend horse in front of a desert backdrop.

Wearing her dark tresses down in loose waves, the 31-year-old’s incredible figure is impossible to miss in her derrière-baring costume.

Irina’s stuns in a denim bodysuit, complete with a thong-style back and plunging neckline, while filling her leather gun holder with bright flowers.

Keeping her cowgirl hat firmly on, the Russian model looks dangerously close to a nip slip in the tiny outfit, featuring brown straps.

Flicking her hair back seductively, Irina makes no attempts to hide her peachy behind before turning her attention to her two male companions.

Adding a leather jacket to her attire, the mother-of-one wastes no time in successfully lassoing a man dressed as a cactus before rolling her eyes at a useless cowboy.

“I love doing LOVE Advent because it’s always fun getting wild and crazy with Katie and it reminds me of old Russian Christmas celebrations,” Irina said of the clip.

It comes just hours after Kate Upton jiggled her assets in a skimpy leotard before bouncing around a court with a tennis racket.

“LOVE Advent is a great Katie Grand tradition. It's silly and fun, and I love shoots where I don't have to take myself too seriously,” the 25-year-old added.

Meanwhile, the previous day, it was Bella Hadid’s turn to get wet and wild in racy red lingerie.
