Baby的詞曲作者兼歌手當然就是當紅的歌手兼演員布蘭妮·斯皮爾斯，而她的《Baby》歌詞是英文的，而英文歌詞clean出現的場景並不清晰，因該歌詞是：
Girls!
Don't you roll your eyes at the boys
Don't you let them take your breath away
You don't have to show them how to do it
You don't have to try so hard
Just remember one thing
Baby, you're beautiful just the way you are
而clean在這首歌中並未出現，可能只是歌詞中的一種意境或形容詞。以上答案請參考，有需要請查閱相關英文資料。
