Mauro Icardi and Maxi Lopez
Icardi and Lopez appeared to be two Argentinian soccer players living the dream. The pair played for Sampdoria in Italy’s Serie A and also represented their national team. But the former friends became bitter enemies after Icardi had an affair with Lopez’s wife, Wanda Nara. It’s safe to say that would do it.

Lopez and Nara divorced but then she married Icardi six months later. Things became even crazier when Icardi got tattoos of Lopez and Nara’s children’s names. Now Lopez refuses to acknowledge Icardi’s existence. Icardi faced a long absence from the Argentina squad because it divided the locker room (via Sport Bible).
