Next time you're watching Ellen's talk show or Party Down or 1/8/08 or what have you, notice how similarly Ellen and Lizzy speak. It comes out with their "-ck"s and "-gg"s, this sound like they're holding the backs of their tongues down far back in their throats. Also I guess the way they might say "orange" would be an example of what I'm talking about. Or if you could imagine them saying "That's crazy."
I wonder if this is a regional accent. I will add other people who speak like this as I find them.
