UK & Australia : Kylie
Americas, Asia: Mariah

The rest are ambiguous. Overall Mimi.

Kylie in the UK and Australia, Mariah everywhere else.

Mariah, obviously.

Mimi

Can't Get You Out Of My Head's bigger than any Mariah Carey song globally.

And Mariah has like 5? albums bigger than any Kylie album globally.

Mariah, she sold more WW.

Yeah and Mariah has like 8 albums that were more successful worldwide than Fever.

Kylie - UK + Australia
Mariah - basically everywhere else (minus a few European countries)

Kylie felt much bigger in Europe. Many people know just AIWFC from Mariah here

Kylie doesn't only have the UK, but the entirety of Europe, though.

AIWFCIY alone is bigger than Kylie's entire career, case closed.

Kylie in Australia and Europe (I think?) doesn't really matter though since the OP is asking WW, which is clearly Mariah by Light Years

Mariah.

mmm

I left it ambiguous cus Kylie is bigger in more of the smaller countries, while France is clearly Mariah and Germany is debatable.

kylie is bigger in latin america, Can't Get You Out Of My Head gets airplay here. I have never heard mimi on the radio.

This.

Lol in Brazil alone she's in the top 10 best selling international female singers ever. Kylie is no where to be found on the list.

Speaking of Kylie, she deserves a success a la Madonna, underrated Queen of Pop and hot boyfriends
