Fausto Xavier Aguilera is best known as the father of singer Christina Aguilera. Born in Ecuador and later serving as a sergeant in the U.S. Army, Fausto married Christina’s mother, Shelly Loraine Fidler, and the two had two daughters together.

His Early Life
Fausto Xavier Aguilera was reportedly born on November 4, 1949, in Guayaquil, Ecuador, to parents identified as Fausto Xavier and Edna Maria Monge Verduga. Little reliable information is publicly available regarding his childhood, siblings, or education.
His Ecuadorian background would later play a meaningful role in shaping his daughter Christina’s connection to Latin American culture and heritage.
His Military Career
Fausto served in the U.S. Army, reportedly reaching the rank of sergeant. His military service meant the family relocated frequently during Christina’s early childhood, and she has spoken publicly about growing up in a military household that moved between different locations during her youth.
Despite her difficult relationship with her father, Christina has publicly acknowledged and shown respect for his military service, sharing photographs of him in uniform while expressing gratitude to service members more broadly for their sacrifices. Specific details regarding when Fausto joined the Army, his length of service, or his retirement date aren’t widely documented publicly.
His Marriage to Shelly Loraine Fidler
Fausto met Christina’s mother, Shelly Loraine Fidler, reportedly while both were attending college. Shelly, who had a musical background and later became known as Shelly Loraine Kearns, is reported to have married Fausto in 1980.
Their first daughter, Christina María Aguilera, was born on December 18, 1980, in Staten Island, New York, followed by their second daughter, Rachel Aguilera, born June 6, 1986. The marriage eventually ended in divorce, though reports differ slightly regarding the exact timing of the separation and Christina’s age at the time. Following the divorce, Shelly relocated with her daughters and later married Jim Kearns, with whom she had a son named Michael.
His Children
Fausto has two publicly known daughters with Shelly: Christina and Rachel Aguilera. Christina went on to become an internationally recognized singer, songwriter, actress, and television personality, while Rachel has led a considerably more private life, with far less public information available about her career or personal activities. There are no reliably confirmed reports indicating Fausto has additional children.

His Relationship With Christina Aguilera
Fausto’s relationship with his daughter has drawn significant public attention because Christina has discussed her childhood openly in interviews over the years. She has alleged that her father was physically and emotionally abusive, and that her mother also experienced domestic violence during the marriage — serious claims Christina has made publicly about her childhood experiences.
Following her parents’ separation, Christina became distant from her father, describing a long period during which the two did not see each other. She later indicated some openness to reconnecting — in 2012, she said she’d be willing to sit down with him in hopes of finding closure, and has also mentioned that Fausto wrote her a letter acknowledging past mistakes. The current state of their relationship isn’t clearly documented in public sources.
Why Christina Kept Her Father’s Last Name
Despite the distance in her relationship with her father, Christina chose to keep the Aguilera surname, a decision that remained important to her even after her mother’s remarriage. She’s explained that at one point during her childhood, changing her surname to her stepfather’s name was discussed as part of a potential adoption, but she chose not to make that change.
She continued using Aguilera throughout her life and eventually became internationally known under her full name, Christina Aguilera.
His Ecuadorian Roots Influenced Christina
Fausto’s Ecuadorian heritage gave Christina a direct connection to Latin American culture from an early age. She’s said that Spanish was commonly spoken around her during childhood, with her mother also speaking the language — exposing her early on to both Spanish and Latin music and culture.
That background remained significant as her music career developed. In 2000, she released the Spanish-language album Mi Reflejo, featuring Spanish versions of some of her earlier songs alongside additional Spanish-language recordings — her Latin roots have continued to inform her music and public identity throughout her career.
Who Is Christina Aguilera?
Christina María Aguilera is Fausto’s oldest daughter and the primary reason for public interest in his life story. Born December 18, 1980, in Staten Island, New York, she began performing at a young age, appearing on The All-New Mickey Mouse Club before launching a major recording career.
Her self-titled debut album, released in 1999, produced hit singles including “Genie in a Bottle,” “What a Girl Wants,” and “Come On Over Baby (All I Want Is You).” She’s since released numerous additional albums, including Mi Reflejo, Stripped, Back to Basics, Bionic, Lotus, Liberation, and Aguilera. Christina has also spoken publicly about how her childhood shaped her adult life, saying that witnessing problems in her parents’ relationship made her determined to achieve financial and emotional independence, and that she’s aimed to create a different kind of home environment for her own children.
His Grandchildren
Through Christina, Fausto has two publicly known grandchildren. Christina welcomed her son, Max Liron Bratman, in January 2008, with music executive Jordan Bratman, her former husband. She later welcomed a daughter, Summer Rain Rutler, in August 2014, with Matthew Rutler.
Where Is He Now?
Fausto Xavier Aguilera has maintained a private life and rarely appears in mainstream entertainment coverage. Most publicly available information about him comes through Christina’s interviews and articles discussing her childhood and family history, with no widely verified public information available about his current residence or daily activities.
His Net Worth
Fausto Xavier Aguilera’s personal net worth isn’t reliably known. Some celebrity websites publish financial claims about relatives of famous individuals without strong supporting evidence, and there are no widely available financial records establishing his personal wealth. His daughter’s financial success shouldn’t be treated as a reflection of his own net worth. There’s also no widely verified public social media account belonging to him, so any accounts using his name shouldn’t be assumed authentic without reliable confirmation.
Final Thoughts
Fausto Xavier Aguilera’s story is defined largely by his complicated relationship with his daughter, Christina Aguilera, whose public accounts of a difficult childhood have shaped much of what’s known about him. Beyond that relationship, his Ecuadorian heritage and military service represent notable aspects of his own background — the former directly influencing Christina’s connection to Latin culture and music throughout her career. While Fausto has maintained a private, low-profile life, his story remains publicly connected to his daughter’s journey toward independence and the complex process of addressing childhood experiences as an adult.
