His long-term partner is Aileen Cavallero, his childhood sweetheart whom he met when they were both teenagers growing up in Santa Rosa, La Pampa. The pair kept their relationship extremely low-profile for the first six years of their romance, only making their first official public appearance together after Mac Allister earned his first call-up to the Argentine senior national team in 2019. They welcomed their first child, a son named Rio, in May 2023, just three months after Mac Allister completed his high-profile £35 million transfer from Brighton & Hove Albion to Liverpool. The couple rarely shares photos of their son on public social media accounts, intentionally shielding his early years from unnecessary fan and media scrutiny to give him as normal an upbringing as possible. Mac Allister comes from a well-known Argentine footballing dynasty. His father, Carlos Mac Allister, is a former Argentine international midfielder who earned three caps for the Albiceleste in the 1990s, and later served as Argentina’s Secretary of Sports between 2015 and 2018. His mother, Silvina Riela, is a retired elementary school teacher who has been a constant presence at his matches across his career, often traveling across Europe and South America to cheer him on. He has two older brothers, Francis and Kevin Mac Allister, both of whom are professional footballers playing in the Argentine top flight: Francis is a midfielder for Rosario Central, while Kevin plays as a defender for Unión de Santa Fe. All three brothers were coached by their father through their youth academy years, and remain extremely close off the pitch. When it comes to his ethnicity, Mac Allister has mixed Irish and Italian heritage, a common ancestral background for Argentine citizens given the mass European immigration waves to the country in the late 19th and early 20th centuries. His paternal ancestors migrated to Argentina from County Offaly, Ireland in the 1860s, settling in the La Pampa province where his family has been based for generations, while his mother’s side of the family traces its roots to southern Italy. Mac Allister has previously spoken publicly about his pride in his multicultural background, noting that it is a core part of his identity as a first-generation Argentine from immigrant families. Despite his multi-million pound salary and global stardom, he still prioritizes annual trips back to his hometown during the Premier League off-season to spend time with extended family, often bringing his girlfriend and son along to introduce Rio to his roots.
