Nicole Kidman is allegedly trying to get pregnant by May. Keith Urban is also reportedly giving up touring to spend more time with his wife, and expand his family.

A source told Radar Online that the 49-year-old actress "desperately wants to try for one more child. But she's been moaning that it's not going to happen while Keith was on back-to-back tours."

"Now he has worked out a gap in his schedule, Nicole's taking him to appointments with all sorts of fertility experts, surrogacy agencies – not to mention trying for a miracle and attempting to conceive naturally," the insider added. "Keith goes back to work in May, so Nicole's given them that deadline," the source claimed. "If it doesn't work, she's giving up."

Urban and Kidman married in 2006 and have two daughters, Sunday Rose and Faith Margaret. In an interview with Daily Mail, the Lion star revealed she would love to have another child in 2017. She said: "In everything that has happened in my life, being a mother has been the overriding thing that has changed everything and made it better. I still have the faintest hope that something may happen to me this year."

"Keith and I would love to have more babies. My grandmother gave birth to my mother at 49. I would be beyond happy and just welcome it with open arms."

She added: "You go through heartbreak again and again and then you start to tell yourself it might never happen. I honestly never believed I would actually give birth to a child, then at 41 I became a mother. After so many years of trying, it was so against the odds. We went through a surrogacy with my second daughter because we wanted another child so much that it hurt. I felt my chances of conceiving again were slimmer and slimmer. And then we got Faith."
