Nicole Kidman goes blonde on the cover of US magazine, InStyle. The actress tells how husband Keith Urban sends her a love letter for every night they spend apart. "For every single night he's away, he leaves me a love letter. "Every single night of our relationship," she tells the March 2014 issue of the magazine, on newsstands now. "It keeps us close." The Moulin Rouge star, 46, says the longest that the pair - who wed in 2006 - has been apart is 14 days. "Keith and I are both gypsies at heart. We can make our home wherever we are. "The girls [their two daughters] are like that too now, so we take them everywhere," she said.
