Who was better before 2000? Who was better after 2000?

For me, Ms. Spears was better before 2000 and Ms. Aguilera was better after 2000.

Britney and then Nasty cristina HAHAHA. Both look better with black hair.

But yeah....before britney got married....she was the queen (In the i love rock & roll video...OMFS!!!! She was so0o0o0o0o hot!!!!)

Cristina went up with her video....dirty??? i think it was called...o0o00 oyeah!!!!

Christina is not nasty.. Also I liked Candyman, Ain't No Other Man and Beautiful.

Christina before and after

I always prefered Avril Lavigne. Christina...

i liked Christina more back in 2000, right now i don't really care about both of them.

This video for me made me think Britney was better in 98.

I dont care about them now but before I kinda liked spears earlier

britney both before and after.
though before i didn't listen to any of her music.

starting to listen to her after 2003
more now even with mess she made when she married that guy.

she produced her best dance album ever and the trilogy of #1 dance gimme more piece of me and break the ice.

and her new single its looking like it going to be another.

xtina have some nice songs but her voice its too overpowering to listening to her for long period of times.

Britney was better before 2000 and Christina is better after 2000
Nowadays Britney SUX!! Her single womanizer is one of THE worst songs i have ever heard in my life!
