During the process of recording her second album , Lopez decided to tweak her image as she began to develop into a sex symbol . She started going by J.Lo , something fans often called her . She subsequently named the album '' J.Lo '' . Released on January 23 , 2001 , it was a commercial success , debuting at number one on the US '' Billboard '' 200 . During the same week , her romantic comedy film '' The Wedding Planner '' in which she starred opposite Matthew McConaughey opened atop the box office . This made her the first woman to have a number one film and album simultaneously in the United States . The album was preceded by the release of its lead single , " Love Do n't Cost a Thing " , which reached number one on the '' Billboard '' Mainstream Top 40 chart . It was followed by the single " Play " . In April 2001 , Lopez launched J.Lo by Jennifer Lopez , her own clothing and accessory company . Lopez felt that " the voluptuous woman was almost ignored " in the fashion industry , and therefore her company specialized in clothing women of all shapes . The following month , she starred in the romantic drama film '' Angel Eyes '' , which performed disappointingly at the box office and generated mixed reviews . After several months , '' J.Lo '' was declining on the charts ; this prompted Mottola to recruit rapper Ja Rule to create an urban-oriented remix of the song " I 'm Real " . This led to the release of " I 'm Real ( Murder Remix ) " , which quickly reached number one on the '' Billboard '' Hot 100 . Its success resulted in '' J.Lo '' being reissued to include the single , which was number one in the United States during the week of the September 11 attacks . '' J.Lo '' became the best-selling album of Lopez 's career , having sold 3.8 million copies in the US and moved over 12 million units worldwide
