LONDON: Actress Nicole Kidman is down with flu, forcing her to cancel a charity trip to Kenya. The Australian actress was to fly to the African nation as part of an initiative launched by the United Nations Development Fund for Women (UNIFEM), reports imdb.com. Kidman planned to visit schools and hospitals in the country and raise awareness about women's rights, but has now pulled out of the tour after falling ill. 'Nicole is deeply sorry that, because she is ill with the seasonal flu, she cannot come to Kenya. The 'Say No - Unite to End Violence against Women' campaign is a top priority and together with UNIFEM she will work to advance this critical initiative,' a representative for Kidman said in a statement.
