Australian actress Nicole Kidman is reportedly upset over her children's American accent.

The Oscar-winning beauty, who is currently holidaying in her native country, was quoted by Femalefirst as saying: "They have American accents, although I wish they did have Aussie accents."

According to the "Moulin Rouge" star, Isabella and Conor - her two adopted children - have managed to make lots of friends in Australia.

"I'm very proud that they get to see this country and be a part of it," she said.
