Huh?
I think the word "vulnerable" quit applying to Britney about the time she quit appearing on The Mickey Mouse Club.
Paris and Britney are two peas in a pod, AFICT.
Britney spiraled downhill when Justin Timberlake dumped her. I find it interesting that Britney is determined to win him back and all of a sudden Cameron Diaz has black hair and who suddenly has black hair (again), but Britney. Pretty obvious, but I guess when you're 25 you don't get the obvious.
