To the OP (wineguy), you're probably thinking of a
podcast excerpt from almost a decade ago where somebody e-mailed Robin about it. And it's true that although she gave reasons as to why she wouldn't do it, she also didn't necessarily say no to the prospect either. Hell, if they actually dummied up some fake magazine covers to go with it, what might that tell you?
I'm sure Robin still would be flattered if someone requested it today, but there's still no way she would do it.
Oh, and here's a working link to the video in the above post. Sorry it's an AVI, but we lived in the dark age of video codecs then.

If any news woman would do it, I'd figure they'd be in a "what have I got to lose" situation. Either someone well established nearing the end of their tenure or someone still relatively new and slowly rising. Nonetheless, I'd still call it a career killer. But dare to dream...
