Who knew Nicole Kidman was such a bad girl? The actress, who kept her lips locked about her 10-year-marriage to Tom Cruise, drops some sultry dish about her love life in an interview with British GQ magazine. The demure Oscar-winner admits that she’s explored everything from monogamy to “obsession” and even “strange sexual fetish stuff” — although it’s not clear when the kinky canoodling unfolded, according to London’s Daily Mail. In contrast to her super-private relationship with Cruise, she describes her current marriage to country-crooning hunk Keith Urban as “a very extraordinary, adventurous place to be: incredibly raw, incredibly dangerous.”
