Born on February 12, 2000 in Quilmes, Argentina. María de los Ángeles Becerra began her career at twelve years of age on the platform Facebook. In 2015, she posted a five-minute-long parody monologue which was seen over one million times in just hours. This encouraged her to create a YouTube channel in which she would later post videos of her talking and singing, vlogs, and dance tutorials.
Since she was a little girl, she was interested in acting, singing and painting, so at the age of seven she began to take singing, musical comedy, dance and body expression classes at Valeria Lynch's academy. At thirteen she began writing poetry and short stories, which she published on the Internet. She also mixed her classes with football (soccer) practice, another of her passions. She played in a field near her house called "Viejobueno”. Trained as a Catholic, she attended a Catholic school from an early age. Later, she convinced her parents to change to a technical college, a career-oriented school, to learn carpentry. However, during her time at the industrial school, she reported having suffered physical violence, sexual harassment and countless situations of discrimination from her male classmates, because she was one of the few women in the institution. On the other hand, Becerra said she suffered from attention deficit disorder, which made it more difficult for her to study.
She began to become visible at the age of twelve, uploading covers. At fifteen, she posted a five-minute parody monologue that had over a million views in just a few hours. This encouraged her to create a YouTube channel, where she would later publish singing videos, vlogs and dance tutorials. However, when her fame grew, she was still in the fifth year of high school and was forced to choose between the videos or her studies, eventually dropping out her studies.
In September 2017 she earned her first nomination for "Favorite Youtuber" at the Nickelodeon Kids' Choice Awards Argentina. In October, she participated in the third edition of the Club Media Fest of Argentina and Paraguay, an event for digital content creators. In January 2018, Hill & Knowlton named Becerra as one of the most influential you-tubers in Argentina, among ten other creators in the country. In August, she received the award for "Favorite Music Influencer". Also, in November, she was pre-selected in the category "Best youtuber" in the second edition of the Martín Fierro Digital Awards.
In September 2019, Maria Becerra released her debut EP 222 in which she fused elements of urban pop and hip hop. In November, she released her single "High", which would later gain a remix version with Argentine singer Tini and Spanish singer Lola Índigo and reached the number-two position on the Billboard Argentina Hot 100. In 2020 and 2021, Maria Becerra was featured in multiple remixes, including "En Tu Cuerpo" with Lyanno, Rauw Alejandro and Lenny Tavárez, "AYNEA" with FMK and Beret, and "Además de Mí" with Rusherking, Khea and Duki, Lit Killah and Tiago PZK. "Además de Mí (Remix)" became Maria's first number-one single on the Argentina Hot 100.
In 2020, Maria Becerra became the first Latin artist to be signed to the indie record label 300 Entertainment. In 2021, she released her second EP, "Animal, Pt. 1" which included the Cazzu-assisted "Animal" and the solo "Acaramelao". Both singles became hits in Argentina, where they peaked at number five and seven, respectively. The EP shifts genres between hip-hop, reggaeton, trap, hip-hop, R&B and hints of salsa, and explores the themes of women empowerment, love and lust. In May 2023, Becerra signs with Warner Music Latina. In August 2023, Becerra signed with Warner Chappell Music.
