I would vote that Jessica would definitely win the Titfight (by the way, there is no way that she is a B Cup if Fergie is a D Cup). Given that they are about the same size (Jessica is heavier than Fergie theses days), I would say that Fergie would wipe up the floor with Jessica in a catfight. Lastly, I believe, overall, Jessica is more attractive than Fergie. Don't get me wrong, Fergie is hot and a great singer but I believe that Jessica has a prettier face.
