Kidman wants to extend her brood

London: Hollywood actress Nicole Kidman wants to have more children with husband Keith Urban and says being a mother has helped make her career more fulfilling.

The 43-year-old actress, who announced the birth of the couple`s second daughter, Faith Margaret, born via a gestational carrier in December, said being a mother made her perform better in her latest Oscar-nominated role in ‘Rabbit Hole’ and she would love to increase her family, reports a website. "I want more children. I love being around that life force. People ask, `Was the film really hard?` Well, it wasn`t hard to find the emotions. It was hard to keep them in, to put them back. And I cannot imagine doing this if I didn`t have children," she said. The screen beauty, who has two adopted children - Isabella, 18, and 15-year-old Connor - with ex-husband Tom Cruise, insists something inside her was "altered" forever when she gave birth to her and Keith`s two-year-old daughter Sunday Rose. "Something happens to you as a woman once you`ve given birth. You change on a cellular level. You change and are altered," she said. IANS
