Maybe they meant among females?
Still she has a lot of impressive achievements.

she performed with MJ too?

The Diamond albums

And she is the only one from debut album.

It's between that and best selling solo teenage artist.
then the 1.3M debut is 3rd.

Britney's sold closer to 10M and were from debut so I like that.
I remember mariah's diamond albums had sales of 7.5M ish when certified diamond.

For females...it's Britney

Yep. Seba usually is perched to shade Britney so it's not surprising.

Only video from the 90 reach 100 million views (BOMT)
November Rain says hi !

Nnnnnggggg @ the desperation to save face

From a female artist. -.-

Consecutive Diamond albums because probably no one will ever do it again, except maybe Adele.

Umm...
