López was married to Argentine model Wanda Nara from 2008 to 2013. The couple have three sons, Valentino Gastón (born 25 January 2009), Constantino (born 19 December 2010) and Benedicto (born 20 February 2012). Nara and López split after her affair with López’s former Sampdoria teammate and best friend Mauro Icardi was exposed. She and López began divorce proceedings in December 2013. Nara and Icardi subsequently married on 27 May 2014. The scandalous nature of the marriage has brought a lot of animosity against Icardi in Argentina, making him a favorite of rumors and unsubstantiated claims by Argentinian tabloids. It has been argued that the, arguably, generalized hatred against him has been an important factor against his being called to the national team, and even prospect calls have been heavily criticized by people like retired star Diego Maradona, who has entangled in bitter exchanges with Icardi on twitter as a result of his marriage to Nara. During an April 2014 Serie A match between Sampdoria and Inter, López notably refused to shake Icardi’s hand, leading the press to dub the game the “Wanda derby”. Two years later, López repeated the history by again refusing to shake Icardi’s hand during a Serie A match against Torino.
