Keith Urban 'Terrified' as Ex-Wife Nicole Kidman Moves On With New Multimillionaire Boyfriend Michael Reinstein

Keith Urban is reportedly "terrified" that Nicole Kidman has found romance with a handsome and wealthy businessman less than a year after their split, RadarOnline.com can reveal.

The country crooner, 58, has found himself in an officially closed chapter of Kidman's life now that she's reportedly dating Michael Reinstein, as photos of the jet-setting couple have emerged with the 59-year-old actress looking smitten.

With Kidman officially moving on, Urban's VIP pass to Hollywood's biggest red carpets appears to have expired, as the Oscar winner was widely viewed as the true A-list draw in the former power couple, who married in June 2006.

"He knows this gravy train is coming to an end. He rode the Nicole Kidman train for a long time. He wouldn't have been invited to the Oscars, the Golden Globes, or the big parties she gets invited to," longtime Tinseltown insider Rob Shuter dished during an appearance on Maureen Callahan's The Nerve podcast.

"Even after the divorce, as long as she was still single, they were connected. He still had the Nicole story to tell," Shuter explained about the power Urban still held following Kidman filing for divorce in September 2025. It was finalized in January.

"If she moves on, it's the end of that chapter. I think he's terrified it's over," Shuter explained about The Fighter singer.

The author of It Started With a Whisper then shared that the former couple's two children, 18-year-old Sunday Rose and 15-year-old Faith Margaret, haven't met Reinstein yet, but cryptically hinted that the girls are still deeply estranged from their father over what really happened that led to his split from Kidman.

"Wait until the kids get to know this guy and meet him," Shuter said.

"They haven't met him yet. I don't think they'll ever speak to their dad again. The kids know what happened. Nicole knows what happened. It will come out. It always does. It'll take a minute, but it will come out," he added about how Urban reportedly moved out of the family house in June of 2025 amid a midlife crisis, months before news of the split became public.

Kidman has primary custody of Faith, while Sunday is no longer part of the agreement since she became an adult in June.

After the divorce, ravishing Kidman remained a single woman until photos emerged of the Babygirl star cuddling up to Beverly Hills private equity investor Reinstein in Portofino, Italy, in mid-July.

The two were spotted enjoying Aperol Spritzes at the iconic Belmond Splendido Hotel, leaning in close for flirty conversations from their side-by-side loungers.

Reinstein was also photographed emerging from Kidman's room, with the actress briefly stepping out alongside him in a slinky white silk camisole and matching skirt.

The businessman, who has a net worth of more than $250million, then picked up Kidman after her private jet landed in California on July 31, pulling up in his $340,000 Ferrari 296 GTB sports car.
