Actress Nicole Kidman and country star Keith Urban have sent out invitations for their wedding, which will reportedly take place next month (MAR06).

Marriage rumours have besieged the couple - who began dating last year (05) - since November, when Kidman began wearing a large diamond ring on her left hand.

Sources tell American magazine Us Weekly the couple will exchange vows in Australia in early March (06).

The source says, "Nicole is an Australian girl at heart. It's no surprise that she would want to get married here."
