A-list red carpet shoe leader Christian Louboutin has outdone himself yet again.
His Spring 2012 "Sex" shoe is the newest celeb favorite and you don't even have to ask why.
The patent nude pointy toe pump valued at $1,395 is so stellar it has appeared on the red carpet twice in the past week, conjuring up the newest fashion faceoff: The Great Kate Debate.
Entering the ring first: Katy Perry at last week's Echo Awards in London, pairing the shoe with a silver futuristic dress by Paco Rabanne and blue updo.
You can get your SEX shoe fix at BarneysNewYork.com but until then, tell us who rocked it better, Kate Upton or Katy Perry?
