Did Gwen stefani write hollaback girl about jaylo?

No, Gwen Stefani did not write "Hollaback Girl" about Jennifer Lopez (J.Lo). The song was primarily a response to being disrespected and is often interpreted as a reaction to a feud with another artist, which many speculate to be related to a comment made by Courtney Love. Stefani has clarified that the song is more about empowerment and confidence rather than a direct reference to J.Lo.
