Keith Urban wants baby with Kidman

Keith Urban has let his wife Nicole Kidman know that he wants to have a baby with her, according to reports.

The country singer has recently been talking about his wish for a child with Kidman to his friends and during his Alcoholics Anonymous meetings.

Urban reportedly let the Cold Mountain actress know his new-found desire by giving her a hand-knitted baby boot as an early birthday present.

A source told Grazia magazine: "She couldn't believe it when she opened it and started jumping around and crying.

"Keith says he finally realised just how much having a baby means to her and how much of their marriage has been previously devoted to his problems."

Kidman, who has two adopted children with ex-husband Tom Cruise and once had a miscarriage, has reportedly wanted a biological child for a while.
