The original Track Masters Remix features 50 Cent. At the time of the single release, Epic Records chose Nas for the radio version. Nas re-recorded new rap verses and the track was cut down to 2:52, becoming the Track Masters Remix Radio Edit. Nas replacing 50 Cent caused controversy; and the rappers, who were previously like "brothers" have resented each other since. The remix's beat contains re-adaptions of the instrumental used on Luniz's 1995 song "I Got 5 on It" featuring Michael Marshall, a song which itself sampledClub Nouveau's 1987 song "Why You Treat Me So Bad".
"You know what me and Nas we was cool we used to be good [sic] I didn't understand his actions. The first thing that started feeling a little off with him was the Jennifer Lopez sh*t. I had done a record on the Jennifer Lopez album right and this after I got shot this is the first thing I'm doing trying to come back out. Irv [Gotti] was running around calling everybody and saying don't do business with these guys you do business with him we are not f*cking with you. At the time they were selling records so people weigh there value by what you can do for them and they were leaning towards Irv and them and they actually took me off the record and put Nas on the record cause she was on Columbia and Nas is on Columbia."
Controversy ensued over the radio version and the album version. Epic Records decided to place Nas on the radio version due to his popularity at the time instead of 50 Cent. 50 Cent became angry at "former" friend Nas. Nas threatened him, stating: "So he's like a kid living in a hip-hop fantasy world. J.Lo is a friend of mine, if she wants to do a record, I'm doing a record with her [sic] 50 was like a little brother to me." In response to 50 cent's constant slamming of the collaboration, Nas stated: "To sum it all up, 50 is still a new artist. I would say he's got a good five to six more albums before I can really respond to him. With my other battles, it was different. This is not really my thing right here". 50 Cent held no hard feelings towards Lopez, but towards Nas only. According to Epic Records, the switch in artists made on the radio version was "purely business". The 50 Cent-featured version appears on the J to tha L-O!: The Remixes album (however, the European version features a no-rap version) while the Nas-featured version appears on the European pressing of Lopez's 2002 album This Is Me... Then. The 2002 U.S. compilation Now That's What I Call Music! Volume 10 also contains the version featuring Nas. Of the original song from J.Lo, Tom Sinclair of Entertainment Weekly called the song "upbeat" but noted that: "I'm Gonna Be Alright for instance — which is based on the Sugarhill Gang's 8th Wonder — is attributed to Lopez and eight other writers (presumably making Jen the ninth wonder)."

Lopez said that the music video of "I'm Gonna Be Alright" was a reminiscent of her thriller film, Enough (2002). During the video, she had to leave a relationship with a "baddy". Lopez explained: "The song relates to the movie that's coming out at the same time [sic] It's about being in a relationship that you know is not good for you but you know you're gonna be OK [once you end it]. [The video] is basically about a day in the life of this girl who has this going on in her head. I also wanted the set in a neighborhood that was real and capture the essence of how I grew up. I grew up in the Bronx — it had the same kind of urban, city flavor. [The video captures] all the essences — guys playing dominoes, girls sunning on the side of the street because they don't wanna take the bus to the beach." The music video was shot on April 16 and 17, 2002. The music video for "I'm Gonna Be Alright" was directed by Dave Meyers and filmed in the Bronx, New York City, features Nas.
The video begins with the atmosphere of a hot day in Spanish Harlem. Lopez and Nas appear singing in front of a barbed wire fence. Lopez sings in the neighborhood about letting go of a relationship that is not good for her, as the local male residents look on and stare. She appears at a barber shop with her then-husband, Cris Judd, and later at a coin laundry and record shop. She is also playing baseball with men on the street. She later dumps one of her lovers on the street. The clip ends with Lopez winning the baseball game. In 2011, a writer from Daily Express likened the sex appeal from her music video for "On the Floor" to that of "I'm Gonna Be Alright", writing: "[Lopez] once told us in song that I’m Gonna Be Alright and now she’s proved it. The curves she displayed when she recorded the hit video nine years ago have been replaced by a leaner, fitter look."
