I came here to agree with this. I'm 5' and 115 pounds and I look smaller than her. So, while I have no idea how much she weighs, I can almost guarantee it's more than that.
@wantingtodotherightthing I'm 5'1 and 121 right now with a fair bit of muscle and about a 1/2 inch layer of fat over my abs. At 5'8, I would estimate Biel at 130 even. Muscle is heavy as shit.
I don't understand the need to report weights that are low. I was really hoping people would get over that by now. It's a number. She looks great and strong, and that's all that matters.
Goes to show how meaningless numbers can be: I'm about the same height/weight as you... but with a fair bit of flab and about a 3 inch layer of fat over my abs.
Probably a publicist or agent pulled a number out of their butt to send along with her head shots when she first started going on auditions and the number stuck. Why risk an idiot casting director turning Biel down for a part because her real weight looks "fat" on paper?
