DUSK, I guess you and I agree that the thing that most turns us off about Britney is that her public image and the reality are so distant/disconnected. At least Christina appears to be honest about herself, however raw that might be.
On the other hand, I'm just not attracted to the Christina coke whore look. I think she's a bit messed up (of course, so is Britney, she's just hiding it!).
