• Ashlee Simpson told SheKnows.com about this track that touches on the cattiness of girls: "'Hot Stuff' is meant to be a fun song. That's it. A lot of things on the record are laughing at situations, poking fun at things (laughs). With that, when you go somewhere and girls give you the mean eye. You're like, 'oh, wow - this is crazy.' 'Hot Stuff' makes fun of that. That song is meant to be a good time."
• The Neptunes produced "Hot Stuff" along with some of the other songs on Bittersweet World, Simpson's third album. Simpson learned that hip-hop heroes move at a different pace than pop stars, and she put in a fair share of 14-hour days in the studio. She said on her record label website: "I have never worked until 4 a.m. before. I wouldn't go in until late in the afternoon and then we'd work until the wee hours of morning if we had it in us. I started bringing a blanket with me. I got a little loopy and punchy late at night, which affected some of the songs. It was so cool for me to be able to step outside of the way I had always done it before and try new things."
