Personal life

Agüero was married to Giannina Maradona, the youngest daughter of Argentine football legend Diego Maradona. On 19 February 2009, Giannina gave birth to their son, Benjamín, in Madrid, Spain. Diego Maradona was there for the birth of his first grandson, while Agüero, then 20, missed Atlético's training session earlier in the day. Atlético offered their congratulations in a statement on their official website. Agüero and Giannina separated in 2012 after four years together. Agüero shares a close friendship with Lionel Messi, his regular roommate during outings for the national team since 2005. He described Messi as being "like a brother" in his 2014 autobiography, Born to Rise, which contains a foreword written by Messi. Agüero's nickname "Kun", which features on his shirt, dates back to his childhood. It was first given to him by his grandparents, due to a resemblance to the character "Kum-Kum" from Agüero's favourite television programme as a child. He stated, "I have grown to appreciate it because it's unique. It's not every day an athlete is nicknamed after a cartoon character!" Agüero has a tattoo on the inside of his right arm inscribed in Tengwar—a form of writing invented by J. R. R. Tolkien in The Lord of the Rings—that transliterates roughly to Kun Agüero in the Latin alphabet. He also has a tattoo on his left arm of his son's name and date of birth Agüero holds Spanish nationality, after being granted citizenship in 2010 whilst playing for Atlético Madrid.
