I'm trying to remember this movie about a lady who lives in the bronx I believe and she wants to be a model she has two kids with this guy and they're always fighting she sleeps with her boss she also has a transexual brother in the movie.. im really trying to remember this song that I know I like but can't remember it for the life of me anybody know what I'm talking about? Help

It's a song from that movie that a latino group band sings it, it's a cover of a old school song I want to say it's a cover of james brown or sumbody of that nature I even remember youtubing it but I can't remember it for nothing, in the video I thnk the guys in the group are at a carnival and singing it
