I'm not a hater, I just think that a gaga did a revolution of FASHION AND OTHER ARTISTS Although not willing to accept have followed this wonderful new fashion era initiated by gaga.
I think Nicki was doing the crazy look think right about when she got her first big album. I do think that Gaga showed that dressing eccentric can be a profitable marketing strategy, so I'm sure it just made it easier for other artists to wear what they wanted to wear.
I guess they were scare that if they wear something different they will have bad criticizes, so they saw that Gaga make it well so they started to do it, well I think that lol
Christina was paying homage to Madonna and was going through the Bionic era, Katy would have done that any way cause she is Katy, Rihanna was going for a darker and more bad ass look for Rated R and Nicki is just plain crazy. lol
I don'T care what you say about others..but FUCK YOU when it comes to xtina. this woman is a fuckin legend, she doesnt need to copy anyone! and she was ALWAYS BRAVE! I don'T know how old you are, but I bet you know her song "CANT HOLD US DOWN". she was one of the first woman in pop business who taught other women to be brave. her fans are called FIGHTERS for a fuckin reason. so no. xtina didnt copy gaga,
