Rubio worked with writers and producers such as Estéfano (mostly), Chris Rodríguez, Armando Manzanero, Juan Gabriel, Christian De Walden, and Richard Daniel Roman.

Follow-up singles "Yo No Soy Esa Mujer" and "Vive El Verano" also performed well on charts internationally.

The latest singles "Sexi Dance" and "Tal Vez, Quizá" are often considered classic Rubio songs.

The singer updated her music and got ready for this new challenge with new producers and songwriters such as Estéfano, Armando Manzanero, Alejandro García Abad, Ralf Stemmann, Christian De Walden, Richard Daniel Román, Ignacio Ballesteros and Juan Gabriel.

In Argentina, she appeared specially at Telemanias where she performed several songs, including "Lo Haré Por Ti", "El Último Adiós", "Sexi Dance", and "Tal Vez, Quizá".

"El Último Adiós" was then released in July 2000 as the second single in Latin America and reached at number one in Mexico, Colombia and Chile.

The controversial music video contained racy love scenes, as well as men and women appearing barely clothed.

"Yo No Soy Esa Mujer" was released as the fourth single from Paulina in April 2001 reaching number seven in the Hot Latin Songs chart.

"Vive El Verano", written by Richard Daniel Roman and Ignacio Ballesteros was released as the album's fifth single in June 9, 2001, charting at number 31 in Italy.

"Sexi Dance" was initially issued as a club-only track in America, but was a success where it reached number 34 on the Billboard Hot Latin Songs chart.

The song also appeared as an English version titled "Fire (Sexy Dance)" of Rubio's subsequent studio album Border Girl.

"Tal Vez, Quizá", written by Armando Manzanero was released as the album's sixth and final single in September 2001.

At the time of its release, Paulina received universal acclaim from critics; most of them acknowledged Rubio's mature perceptions.

"[8] Joey Guerra from Amazon highlighted the majority tracks while summing the album up as a "most diverse and mature", and acclaimed Rubio as the "Latin pop for the new millennium.

"[9] In an enthusiastic retrospective review, Apple Music complimented Rubio's fushion of contemporary pop/Traditional Mexican folk music crossover, writing, "[Paulina] shows a mix in an explicit way and is a sonic walk through different styles and intensities, with extracts from ranchera, bolero, electronic pop, ballads and guitar rock."

[20][21] According to a report from EFE, those sales came mainly from United States, Mexico, Spain, Colombia, Central America and Venezuela.

With its success, Rubio held the record for the highest 2001 sales by a Latin artist and in total was certified 8× platinum for the shipping of 800,000 copies in the U.S alone.

The album was certified Gold and Platinum in Mexico, U.S, Colombia, Central America, Venezuela, Spain, Argentina and Chile.
