Keith Urban ‘Shamelessly’ Flirted with ‘Other Women’ While Married to Nicole Kidman (Exclusive)

Since Keith Urban’s split from Nicole Kidman, fans have flagged the country star’s cozy on-stage relationship with his guitarist, Maggie Baugh — but a source tells the National Enquirer his behavior behind the scenes was worse than anyone knew.

Long before the Babygirl actress, 58, filed for divorce on Tuesday, September 30, the “Stupid Boy” singer, 57, “totally checked out of the marriage,” says the source, “and took things to a whole new low by shamelessly flirting with other women.”

Around the time that the Oscar winner’s mother died in September 2024, “she desperately needed love and serenity from her husband,” adds the source, but instead she heard rumors of his “womanizing.”

“She chose not to believe them at the time,” adds the source. “It seemed totally incomprehensible to her that the love of her life would be capable of such horrific betrayal and cruelty.”

Kidman is finally realizing that now and she’s “furious,” says the source. “There’s no sugarcoating the fact that Keith behaved like a total jerk and treated Nicole like dirt at a time of her life when she was most vulnerable.”

While insiders close to the country star told TMZ they blamed his behavior on a “midlife crisis,” the source argues that his treatment of his wife of 19 years is “on another level. For Nicole, it’s truly the stuff of nightmares.”
