Nicole Kidman keeps her form with a morning Pilates class in Los Angeles August 8 morning. To avoid causing a stir up front, Nicole entered and exited the gym through the side entrance.

She may be nearly 40, but Nicole was recently announced as Hugh Hefner's top pick of Australians to feature in Playboy.

"(Kidman)'s bewitching, and the vision of her with a cigarette in one hand and her knickers in the other as a delicious French au pair will haunt my fantasies for months," he was quoted by Contactmusic, as saying.
