Based upon rudimentary Internet search criteria, it would seem Bjr99 has more or less given accurate numbers for Ms. Lopez. And while my "eyeball" test says Ms. Kidman-Urban is certainly less "weighty" than J-Lo, her slender build and taller height may give the illusion of a lesser weight. So I withdraw my contention (graciously!)
Anyone who tries to find "accurate" weights for celebrities is going to sooner or later, end up banging their heads against a wall (or other immovable object) for none of them will allow accurate numbers to be revealed once they pass the point in their careers where they are able to regain control of information.
Jen just LOOKS heavier, stronger, more solidly constructed - by about 10 pounds. (My goodness, her derriere alone probably weighs more than Kidman did in her prime!)
Yet, being proved wrong- won't effect my vote for Lopez for being the one I see winning this fight!
