Referring to Jessica Simpson as a 90s icon just doesn't describe her impact for me. I guess people say since her first album and single came out at the end of 99 then she's a 90s act but I def consider her 2000s.
Her first single was popular in 2000 tho. It literally came out mid 99 and got popular at the turn of the New Year - she's a 2000s act. I remember my dialup internet buffering so I could stream internet radio to hear "I Wanna Love You Forever" lol
