Back in 1999, Jennifer Lopez collaborated with rap heavyweights Big Pun and Fat Joe for the groovy and uplifting "Feelin' So Good." It was the fourth track from her debut album, "On the Six." The track's infectious beat and catchy chorus captured the essence of pure joy, marking the beginning of J. Lo's journey in hip hop. The song was released in January 2000. And, sadly,  Big Pun passed away that same month at 28 years old. 

Jennifer Lopez and Ja Rule joined forces for the No. 1 Billboard Hot 100 hit "I'm Real (Remix)" — which was released in 2001. Although the song received backlash for Lopez using the n-word, the song was an international hit. 

Released in 2002, "All I Have" featured hip-hop legend LL Cool J. The track was an instant sensation that dominated the charts and the hearts of millions worldwide. The track showcased J.Lo's prowess in both singing and rapping, blending seamlessly with LL Cool J's smooth flow. The song's heartfelt lyrics and irresistible groove made it an anthem of empowerment and resilience, resonating with audiences of all ages. "All I Have" was her fourth No. 1 single. 

"I'm Gonna Be Alright" from Jennifer Lopez's album "J to tha L–O! The Remixes" marked a significant milestone in her career. The song's upbeat tempo, infectious rhythm and empowering lyrics made it an instant hit on the airwaves. With Nas' confident verse, the track became a powerful anthem of resilience and overcoming obstacles. The song charted at No. 10 on the Billboard Hot 100.

Jennifer Lopez's chemistry with LL Cool J was undeniable. And it was evident once again in "Control Myself." Released in 2006, the song was a high-energy, club-ready track that dominated dance floors worldwide. The track peaked at No. 4 on the Billboard Hot 100.
