Nicki is rapper...

GAGA, RIHANNA AND NICKI :*

Whos the 6th?

nicki looks pissed off!!! lol

Beyonce, LADY GAGA,Katy, Ke$ha, Riri, P!nk, Nicki, Britney <3 <3 <3

Gaga and Britney were the only women (after Madonna) who have revolutionized the Pop Music.They're the queen.

Ke$ha *--* <3 and Lady Gaga Queen <3 *----*

I like them all, don't like all their music. But when you try to put the voices together, I think Katy Perry, Kesha Rihanna en Nicki's voices don't match with gaga's voice

They should all come together and do a collab. it'd be like an 8 minute song though....but being a person that has listened to almost every single lady gaga song, i'm used to 8-minute long songs....XD

so beautiful ! beyonce,lady,katty,ke$ha,rihanna,pink,nikky,britney!!! divas!!

Bey + Gaga + Ke$ha + Britney

all are queens , exept niki and katy....

P!nk,Ke$ha and Gaga <3

I don't think Nicki is Pop

QUEENS!
