As Rubio says "I have been famous since I was born", as she is the daughter of Mexican actress Susana Dosamantes and Enrique Rubio, a lawyer of Galician ancestry. Rubio was born in Mexico City, Distrito Federal, Mexico. Rubio has a younger brother named Enrique.
On April 30, 2007, she married Spanish public relations executive Nicolas Vallejo Najera "Colate" in Xcaret, a park on the Mayan Riviera in Cancun, Quintana Roo.
At age 5, Rubio was taking singing, acting, jazz, painting, and dance lessons while enrolled at what is now the Centro de Educación Artística (CEA) in Mexico. After two years there, Rubio's parents were contacted by Julisa and Guillermo del Bosque for approval of Rubio's joining a band that would be formed by children from the center.
On April 30, 1982, she began her career when she was ten, under the guidance of Miguel Bosé and debuting in a children's pop group Timbiriche. The original band had seven members: Alix Bauer, Benny Ibarra, Diego Schoening, Mariana Garza, Paulina Rubio, Sasha Sökol, and Erick Rubin (who joined a year later). Rubio recorded 11 albums as part of Timbiriche. In 1985, Timbiriche participated in the musical Vaselina (Spanish adaptation of the American musical Grease). While in Timbiriche, Rubio turned to acting in telenovelas with Televisa. She landed her first role in 1988, as the villain Paulina Montenegro in Pasión y Poder (Passion and Power). In 1992, also starred in Baila Conmigo (Dance With Me) as Andrea, one of the biggest telenovelas of that year. Two soundtracks, Baila Conmigo and Recuerdos de Baila Conmigo, were released. Members of the soap opera made television performances on Siempre en Domingo (Always on Sunday), among other TV programs.
In 1991, Rubio left Timbiriche and focused on launching a solo career. She traveled to Spain to begin work on her first project as a solo artist. In 1992, she released her solo debut album, La Chica Dorada under the EMI; La Chica Dorada became her trademark nickname. La Chica Dorada was certified Diamond in 1997, and she was presented with an award during her promotion of Planeta Paulina on Veronica Castro's extinct music show, La Tocada. After reissues in countries including Mexico, USA, and Spain, the album "La Chica Dorada" sold 2.5 million copies. The first Mio is Rubio's signature song and peaked at #3 on the Billboard Hot Latin Tracks while reaching #1 on Mexico. Amor de Mujer, Sabor a Miel, and Abriendo las Puertas al Amor were released as the following singles reaching #22, 8, and 9 on respectively on the Hot Latin Tracks.

In 1995, El Tiempo Es Oro was released. It includes the hits Te Daría Mi Vida and "Nada de Ti" which peaked at #1 in Mexico while "Hoy Te Deje De Amar" peaked at #9. The theme song and title to the 1994 Mexican film Bésame En La Boca, is included on the album, in which she also starred.
In 1996, she released her last album with the EMI Latin record label, Planeta Paulina, which included the hit single Enamorada which peaked at #2 in Mexico. "Enamorada" was featured as the theme song of the 1995 telenovela in which she starred as Alma, Pobre Niña Rica. Rubio also recorded English versions of the songs which did not appear in the album. Some of these would be released years later in a hits compilation. The first single of the album "Simpre Tuya Desde La Raiz" peaked at #1 in Mexico while Solo Por Ti peaked at #7.
After Planeta Paulina, Rubio took the longest retirement of her career. She left the music scene and moved to Spain where she did a little bit of everything. Except for her participation in 1998's Reencuentro Tour with Timbiriche, Rubio was absent from the music scene for nearly four years.
In 2007, Paulina launched her own "lipstick" in partnership with M.A.C. titled "Rubia". Paulina stated, "I love wearing make-up and use MAC products on stage and off, it's suitable for all occasions. I was thrilled when M.A.C approached me to create a new shade of lipstick and I instantly thought it should be a bold, vibrant matte lipstick that will look sexy on all women."
In 2008, Paulina launched her own "fragrance" titled "ORO". The fragrance was released and created in conjunction with "Oracle Beauty Brands". It is an elegant floral oriental array of sparkling citrus that is awakened by hints of espresso bean and peppered florals, while being sweetened by a touch of vanilla. "This fragrance is for women like me who believe in themselves; are strong, fun and unpredictable, yet tender and loving. I put so much creativity and love into this fragrance, I feel as if a drop of me is in each and every bottle to be shared with my fans and all women", said Rubio.
Paulina has a restaurant in Miami Beach called L’Entrecote de Paris.
In 2007, Paulina joined the "Latino Commission on AIDS", an organization in the fight against the spread HIV/AIDS in the Latino community. Paulina became the first "Mexican Madrina" to parter with the organization. Paulina stated, "It is important to make our voice heard and try to bring back some of the care that the community shares each day".[11] Rubio has been part of several videos in which she asks viewers to promote "safe sex" relationships in order to prevent the spread of sexually transmitted diseases.
In October 2007, Rubio was in a government probe about whether or not she had desecrated Mexico's flag. The Spanish edition of Cosmopolitan featured her apparently naked underneath a red, white, and green sheet. The Mexican government said she may have violated an article in the National Flag, Shield and Anthem Law, which states that "private individuals will give the appropriate respect to the national symbol and handle it with care." The offense can be punished by fines ranging from $45,000 to $50,000 MXN (Mexican pesos) and jail time of up to 36 hours.[16] However, in a published report, her mother, Susana Dosamantes, said that the artist did not authorize such photos.
By 2009, Paulina released her ninth album named “Gran City Pop”. “Causa y efecto” was the first single of the album and both (album and single) peaked the 1st places at Billboard Magazine, iTunes, and latinamerican radio charts.
