You've got to be kidding me.
So many young artists have tried to do her vocal runs and riffs.
Christina was always able to put sing Britney and honestly she NEVER was imitating Britney's sound. Christina always worked with different producers while Britney and Pink worked with the "hit makers".
She has never looked like the two. Any comparisons were made only because they are white females in the industry.
She is a legend with those Grammy performances alone. And her tours were some of the top grossing during its time. Her B2B tour was the highest grossing female tour of that year.
She was the catalyst who started working with Sia in 2009 because she was a fan of Zero 7.
She was the first pop collaboration for Nicki Minaj on Bionic.
The only thing working against her career at the moment is that she puts her kids first. Can you really get mad at someone for that?
