Good lord this woman is beautiful. I wasn't quite seeing it from the still pictures, but video loves her.
I don't think she's bored, as has been suggested, I think she's just got kind of a low drawly voice.
We shouldn't expect TOO much from the lady though. She's mainly a host, and only secondarily a marginal food personality--a decent cook who had enough presentation skills and certainly enough magnetism to be presentable on TV after writing a vanity cooking book. Nothing wrong with that, but we need to keep it in perspective.
And she's much better than Katie because she comes off as a woman and not a child. She can still be eye candy, she's just appropriate eye candy.
