"No, I just have a little tummy," says the 41-yer-old actress – whose form-fitting dress had some bloggers speculating about a possible "baby bump" at Tuesday's premiere of her new film, Australia. She laughingly adds, "My god, I just had a baby four months ago – give me a break!"
Kidman made the declaration Friday, when she called in to the "Kyle and Jackie O Show" on Sydney's 2DAY F.M.
"I think I've always had a little tummy, though, it runs in the family," says the notoriously slim star. "My sister does, my mum does, my grandmother did .... We affectionately refer to it as the 'little tummy.' "
The Oscar winner also gushed about her new daughter, Sunday Rose, with husband Keith Urban. "I'm just completely besotted with her," Kidman said. "She was singing up a storm this morning .... She's just discovered her voice. She's high and low. Other people may call it screaming – but not to me!"
Congrats to Hugh JackmanKidman also sent her best wishes to her Australia costar, Hugh Jackman, who was recently named PEOPLE's Sexiest Man Alive.
"Isn't that fantastic?" she queried.
"He really is so nice and really, really genuinely is one of the easiest guys to be around," added the actress, who has a Manhattan apartment in the same building as Jackman and his wife, Deborra-Lee Furness. "And he always manages to see what's good."
