Upon its release, the album received generally mixed reviews from music critics, who criticized its manufactured sound, while praising its Spanish and dance material. Commercially, "J.Lo" debuted atop the US "Billboard" 200 the same week as her film "The Wedding Planner" opened at number one at the domestic box office, making Lopez the first entertainer to have a number one album and film simultaneously. The album was certified quadruple platinum in the United States, making it her highest-selling to date, and became the sixth most successful album of the year worldwide.
