The 45-year-old actress, who will be seen on a cover and spread of a leading lifestyle magazine, wears looks by designers like Emilio Pucci, Missoni, Oscar de la Renta and Versace in the special issue, reported People magazine.
"I find standing and posing for photos very awkward," she said.
Kidman, who was once married to Tom Cruise, said her priorities have changed as she is getting older.
"As you get older... All of that other stuff becomes less important. Like, I've always had a little belly. I mean, now that I'm 45, they don't say, 'Oh, she's pregnant!' as much. But I've got skinny arms and legs, and then I've got a little belly," she said.
