Nicole told her pregnant interviewer: "I had my last one at 43. My grandmother had her last at 49. Every month, I'm like: "I hope I'm pregnant!" (to which her publicist replied "Off the record") "Off the record"? I don't mind! Why not, right? I wish I was!"

Nicole Kidman is breathtaking in Calvin Klein Collection on the cover of Elle magazine's January 2015 issue, on newsstands December 16.

Kidman, 47, opened up to the mag about marrying Keith Urban after a month of dating: "I'm spontaneous. I jump in. I kind of like getting married and then getting to know each other; I know that it sounds incredibly strange, but to me, it's a more natural process.

Kidman also talked about her good friend Sheryl Crow: "I think that she has been very poised throughout her public life, and sometimes people will misconstrue that; they see her as being an ice queen. The kind of scrutiny she's been subjected to can't be comfortable, and she's dealt with it by being very careful - that's what gives people the wrong idea. She's not someone we're going to see out paddle-boarding in a G-string; she doesn't set up situations where she's playing to the paparazzi. She's more old-school than that. She's not that kind of movie star."
