We all know Beyoncé and Britney Spears were two of the most of successful female singers between the years 2000-2009 and they are still as successful.

But who was the third most successful female standing next to them? Who had impact in the pop music as much as they did? Discuss and don't forget to vote.

P!nk.

P!nk

I'll take Alicia Keys out of those three. And I never even heard an album by her.

P!nk.

Alicia

shakira

P!nk | Christina | Britney

Finally "Shakira" is an option in such ATRL polls

Rihanna is increasingly big since 2005.

This. Plus she sold 50 mil in that decade, more than the others I think.

Whenever Whereever and Hips Don't Lie make it hard to ignore her.

Billboard named P!nk the #1 pop musician of the decade, so her

Christina up until 2006.

Not sure on the other. :/

Definitely Christina.

It was Christina, Britney, & Beyonce for sure
