I am really hoping this News of the World “exclusive” turns out to be true, because I hear a new Nicole Kidman pregnancy story at least once every two weeks and its getting a tad bit repetitive. Surely she must be carrying, like, thirty babies in her tummy by now at this rate?

HOLLYWOOD beauty Nicole Kidman is pregnant, the News of the World can reveal. Friends of the movie star have told us she is “over the moon” after learning this week she’s expecting a baby.

Nicole and husband Keith Urban, both 39, have been trying for a child since they married in June last year.

And now the pal has revealed: “They’ve managed it. They are both absolutely delighted. Little Urban Junior is on the way.”

The thrilled mum-to-be got the happy news during an hour-long visit to the St John’s Health Centre in Santa Monica, California, where ex-Spice Girl Mel B gave birth to daughter Fortuna Daphne Bay.

News of the World stories tend to be a bit hit or miss, so I wouldn’t be registering to Nicole and Keith’s Petit Tresor baby registry just yet. It would be very good news for Nicole if she was–her BFF Naomi Watts is preggers at the moment, and nothing makes a pregnant woman feel better than having her best friend be pregnant at the same time so she can have someone to relate to.

Speaking of Naomi Watts, she gave an interview to YOU magazine for this week’sThe Mail On Sunday and although she was happy to confirm her pregnancy, she seemed to come across as wanting to keep it as much a private affair as possible (unlike other pregnant women in recent history like, say, Tori Spelling). I’m sure if Nicole was pregnant, the last place she would want to announce it would be the News of the World.

Update by Celebitchy: Nicole’s publicist says she is “100 percent not pregnant” and that is about to go bareback horse riding in the Australian outback, which she probably wouldn’t do if she were knocked up.
