Kidman keeps quiet on Cruise-Holmes affair

Nicole Kidman is being careful not to cast judgment on ex-husband Tom Cruise's relationship with younger actress Katie Holmes.

When asked in May about Cruise's very public romance with Holmes, Kidman didn't address the subject directly.

However, when asked about photographic publicity stunts in general, Kidman has told Vanity Fair, "In terms of your life, if you start to exploit it, then what's real, and what's not? What's yours, and what isn't?"

Kidman and Cruise divorced in 2001 after almost 10 years of marriage. Cruise was photographed in Rome with Holmes in April, and later confirmed they were dating.
