The superstars, who grew to become one of the entertainment industry’s most stable and iconic couples, have reportedly been living separately since before the summer. Though it was Kidman who formally filed for divorce earlier this week, People have cited insider sources who claim the Oscar-winning actor fought desperately to save the marriage.

An official reason for the high-profile split hasn’t been given, but numerous reports speculate that there have been cracks in the relationship for some time.

One said crack may have come as a result of Kidman upping her workload in recent years. The celebrated actor let her schedule slow to a near standstill when her two daughters by Urban, Sunday and Faith, were younger.

Indeed, back in December 2024, Kidman told CBS News that she had thought to herself “I’m pretty much done now” with acting after welcoming Sunday. Yet her mom, who passed away in September 2024, ultimately changed her mind.
