Irina Shayk is the World Cup’s hottest soccer WAG. She appears in the new issue of Maxim.

Irina Shayk, the hottest of the World Cup’s “WAGs,” shows in a sizzling new Maxim photo spread why one of the game’s hottest super-studs, Portugal’s Cristiano Ronaldo, keeps running and running and running…

WAGs is the not always complimentary acronym for the “wives and girlfriends” of the world’s top soccer players.

They are a bevy of beauties who do their best to fend off the rabid groupies and fans who follow the teams and their superstars.

Irina,28, who has her own career as a swimsuit and lingerie model, has defied the critics by maintaining a steady relationship with Cristiano for more than four years.

They started dating in 2010, and stuck together after Ronaldo, six months into their relationship, announced that he had a son out-of-wedlock from a one-night stand with a waitress.

The 5-foot, 10-inch tall beauty has just made her film debut in the 2014 film “Hercules.” She plays the strong-man’s wife opposite Dwayne Johnson.

Before that, she repped for a slew of fashion brands, covered numerous fashion magazines and has appeared in the Sports Illustrated Swimsuit issue for seven straight years (2007-2014).

Not bad for someone who was once voted “Miss Chelyabinsk 2004,” a beauty contest in her hometown in Russia, where she grew up.

She gets her exotic looks from her father, who was an ethnic Tartar, a descendant of the fierce warrior-nomads who once roamed the Russian Steppes.

Check out her photos and see why Christiano keeps his eye on the ball. Be sure to follow TheImproper on Twitter for the latest celebrity news.
