I don't think so... this was released in 2004. Before early 2009, her voice was extremely different compared to her current voice, so imagine her voice in 2004.

I’ve thought about that. It may still be the slightest possibility, considering Gaga was around 19 and could’ve potentially just have started recording small parts for other artists. I don’t know, it was probably a stretch but worth asking ☺️

Background vocalist on 'Fashion!' is not RuPaul; it, most definitely, is will.i.am, one of the producers of the song.

Ok, thank you so much! I knew will.i.am was a producer of the song, yet I was unaware if he was the backing vocalist, thanks!! 😊
