Is Jennifer Hudson too Skinny?

I like Jennifer Hudson. And I'm proud that she's made her health a priority.  But there is something about the songstress at the Academy Awards Sunday night that makes me nervous. It's not that she didn't look fabulous in her luminescent, orange Versace gown. It just seemed to me - that the fire in her eyes was gone. Fit and toned is one thing, but Hudson has lost her glow. And that concerns me. There is no need to rehash the tragedy that happened to her and her  family, but often times - after a tragedy - we try to remake ourselves to gain control of what happened. All together, Hudson has lost over 80 pounds. And that's commendable, but when look at her, I get a sense that she's making herself into something that she's not,  rather than being who she is. And who she is adoreable. What do you think about Jennifer Hudson's weight loss? Is it too much?
