Nicole Kidman has enraged Aboriginal leaders by breaking a taboo against women playing the didgeridoo.
According to Washington City Paper the actress was seen blowing into the wooden instrument on a German TV chatshow recently.
Cultural leaders in her native Australia have criticised her because their tradition dictates that only men should play the didgeridoo.
One critic has even suggested Kidman's fertility could be at risk after she broke the ancient rule.
Aboriginal actor and language teacher Richard Green says: "People are going to see Nicole playing it and think it's all right.
"I will guarantee she has no more children. It is not meant to be played by women as it will make them barren."
Alan Madden, a cultural officer at Sydney's Metropolitan Local Aboriginal Land Council, adds: "I presume she doesn't know, otherwise she wouldn't be playing it."
