Real Madrid forward Cristiano Ronaldo is the center of attention in England with his return to Old Trafford to face his former team Manchester United on Tuesday in Champions League play.

The Portuguese star also has a high-profile girlfriend, who is no stranger to the limelight, as well. Photos of Irina Shayk were posted by The Daily Mail before the much-anticipated match, as well as several other "WAGs."

Shayk is a Russian model that has made appearances in some of the most popular publications around the world. She’s been featured in the Sports Illustrated Swimsuit Issue between 2007 and 2012. While Kate Upton has been the cover model for the past two years, Shayk was on the cover in 2011.

The 27-year-old is considered to be one of the most beautiful women alive, and has been named so by multiple magazines. Complex Magazine once put her atop their list of “50 Hottest Russian Women.” Two years ago, the Hungarian magazine Periodika named her the “Sexiest Woman in the World.”

Ronaldo and Shayk have been dating for just fewer than three years. According to the New York Post, the couple met when filming and ad campaign for Armani Exchange.

Below are some pictures of Ronaldo’s girlfriend.
