world's most beautiful referee...

          

21-year-old Russian Football referee Ekaterina Kostjunina isn't just loved for her officiating skills on the pitch but for her sultry pictures she always uploads on Instagram.

The Russian beauty takes charge of youth games in Russia but keeps describing herself as a “football player and university student” on IG.

Football fans also love her because of her sexy figure, and the fact she's a referee at the young age of 21, that's not common with female football referees. Her thigh gap though!
