This is what i don't get from most of the girls. They upload multiple pictures like 752242 to fb/twitter yet they find foot fetish creepy. Cristina herself has said that she doesn't like the "attention" her feet get, well bitch... stop posting this type of pictures or deal with the fact that you have a massive fanbase thanx to your feet.
Well, she's not a fetish model, she's a singer. In her position you'd probably want the primary focus to be on your voice. But the in the interviews I've read with Cristina she's mentioned more than a few times that she has foot fans, and overall the vibe I get is she's cool with it.
