María Fernanda Blázquez Gil (born 21 July 1973), known professionally as Fey, is a Mexican singer and songwriter. She rose to prominence with her first three studio albums, which established her as a teen idol and fashion icon in Latin America during the 1990s.

Fey made her recording debut in 1995 with her self-titled album, which was certified platinum in Mexico. She followed it with Tierna la Noche (1996), which peaked at number ten on the Billboard Top Latin Albums chart and number six on the Latin Pop Albums chart in the United States. The album was also certified platinum in Mexico and earned her the Billboard Latin Music Award for Female Pop Album of the Year. Her third studio album, El Color de los Sueños (1998), was certified double gold in Mexico. During this period, several of her singles—including "Ni tú ni nadie", "Subidón", "Las lágrimas de mi almohada", "Muévelo", and "Azúcar amargo"—reached the top 20 on Billboard's Hot Latin Tracks and Latin Pop Airplay charts.

During the 2000s, Fey released the albums Vértigo (2002), La Fuerza del Destino (2004), Faltan Lunas (2006), and Dulce Tentación (2009). La Fuerza del Destino received a nomination for the Latin Grammy Award for Best Female Pop Vocal Album. Having sold more than 10 million records worldwide, Fey is one of the best-selling Latin music artists. She also became the first female solo artist to draw more than 95,000 attendees across 10 performances at the National Auditorium.

María Fernanda Blásquez Gil was born on the July 21st 1973 in Mexico City, to Spanish bassist Fernando Blázquez and Argentinian singer Josefina Gil of the duo Las Gil. She has a younger brother named Francisco "Paco" Blázquez Gil.

The first time she sung on television was at 10 years of age, on the program XE-TU where she sang "No me puedes dejar así" with singer Luis Miguel.

Fey's parents' separated during her adolescence, after which she moved in with her aunt, Noemí Gil, due to being unable to accept her mother's new relationship. Unlike her parents, Noemí supported Fey's wishes to become a singer, even taking her to singing and dancing lessons without her parents' knowledge.

She later met Mauri Stern, of the group Magneto, with whom she began a romantic relationship. In mid-1994, after being rejected by several record labels, she signed a contract with Stern and Magneto's manager, Toño Berumen, to record her first album.

Fey released her first album, titled Fey, in 1995, through Sony Music (Mexico). Within a couple of months of the album's release, Fey had scored several hits in her native Mexico, and had reached No. 1 with "Media naranja", "Gatos en el balcon", "Me enamoro de ti" and "La noche se mueve". Fey toured Mexico, including consecutive concerts at the Teatro Metropolitan, and all of Latin America, and reached Gold record sales by the end of the year. In 1996 Fey released Tierna la Noche. "Azucar Amargo", the CD's first single, stayed in the Billboard chart for more than 30 weeks. Her tour, Tierna la noche, was also successful. Overall the tour consisted of more than 40 presentations in Mexico, the U.S. and Latin America, as well as some presentations in Europe. At the 9th Lo Nuestro Awards, Fey received a nomination for Pop New Artist.
