Irina Shayk, who often strips to her underwear for modelling campaigns, promoted flip flops in nothing but little white shorts.
Wearing only a pair of tiny white shorts, the 26-year-old model is seen holding a pair of red flip flops over her chest to protect her modesty, the Daily Mail reported.
In another publicity short for the brand, she can be seen kneeling on a chair, wearing a tiny pair of denim cut-offs and a short-sleeved shirt tied above the waist to reveal her trim stomach.
The Russian model, who is known for her appearance on the cover of Sports Illustrated Swimsuit Edition, has been dating Portuguese football player Cristiano Ronaldo since early 2010.
Irina, 26, has done a series of top modelling campaigns, including one for fashion giant Armani Exchange — which was reportedly how she met her boyfriend.
