Pale skin can be just as beautiful as tanned skin, in some cases even better. Nicola from Girls Aloud has recently discovered that she looks better without trying to bronze herself to silly levels and she's started to encourage others to be happy with who they are and what they look like.
As for Nicole Kidman, she looks great in that photo but as Sage Mother said, how long was the editor of the magazine working to make her look that good? I'm sure if I met her in real life she'd be quite different to that, but still very, very beautiful. As for the quote above, I have absolutely no reason to doubt her.
