Christina does a better Britney than, well, Britney. I never thought they had much in common vocally, except their age. Britney does her thing, but I don't think she can do anything more than that one genre. Xtina, she has the voice, like Steve Perry. That one in a million-on par with Whitney Houston.
I dig her vocals and think she is above even Mariah. Not to mention she is a longtime LGBT supporter, long before it was a cool thing to attach herself to. I love that she has found herself an average Joe and made a happy little family with her super cute babies.
