Nicole Kidman & Keith Urban’s Alleged “Open Marriage” Drama: Did Guitarist Maggie Baugh Spark Their Breakup?

Nicole Kidman and Keith Urban are making headlines again — but this time, it’s not about a Hollywood red carpet or a country music hit. Multiple insider reports have painted a picture of a long-simmering marriage arrangement, new romantic entanglements, and an explosive divorce filing. And at the center of the latest storm? Rising country guitarist Maggie Baugh.

A Marriage of “Mutual Arrangement”

Rumors about the couple’s unconventional relationship have swirled for years, but a new claim shared on the Deux U podcast from DeuxMoi is putting everything under the spotlight.

According to an unnamed insider, Kidman and Urban had allegedly maintained a “mutually consented arrangement” — essentially, an open marriage. “It was an open secret in the movie and country music world,” the source said. “They lived separate lives for years.”

The philosophy behind it was allegedly simple: “What happens on film sets or music tours stays there.” Both stars were reportedly allowed to have private entanglements outside of their marriage, as long as it didn’t spill into the public eye.

But after years of going along with this so-called agreement, Urban allegedly had a change of heart. According to the insider, the country singer “was tired of pretending” and “wanted to live like a single man” without having to hide. And this is where the rumors about his closeness to a younger band member began heating up.

Keith Urban and Maggie Baugh: More Than Just Music?

Speculation around Urban’s relationship with Maggie Baugh started earlier this year. In April, the 25-year-old guitarist joined Urban on stage after being invited to perform with him at the CMT Music Awards. Not long after, she officially became part of his touring band.

Since then, the chemistry between the two has been noticed by fans and insiders alike. Urban was caught on video during a live performance, singing “I was born to love you” while locking eyes with Baugh. More recently, he reportedly changed lyrics in a love song he once wrote for Kidman — turning it into a dedication to Baugh.

Sources told TMZ on September 30 that Urban was already “involved with another woman” amid his split from Kidman. “It’s all over Nashville,” one insider claimed. Daily Mail later identified the woman as Maggie Baugh.

Baugh’s father was asked to comment on the rumors. While he didn’t confirm anything, he also didn’t deny it. “I don’t know anything about it, other than she’s a guitar player for him,” he said. “I think it’s more of a musician thing than a dating thing.”

Meanwhile, RadarOnline reported that Urban had also spent time with another woman in Nashville over the summer, shortly after moving out of his shared home with Kidman.

Nicole Kidman’s Alleged “Divorce Sneak Attack”

While Urban may have been ready to take his new relationships public, the insider claimed Kidman was determined to maintain the image she had carefully built in Hollywood. The original plan, according to the source, was for the couple to issue a “diplomatic joint statement” announcing their split — a quiet, elegant separation.

But allegedly, Kidman flipped the script. The insider claimed she hit Urban with a “divorce sneak attack,” filing first to control the narrative. She officially filed for divorce on September 30, citing “irreconcilable differences.”

Shock, Image, and Humiliation

Friends of the Oscar-winning actress say the rumors of Urban’s romance hit her hard. One source told RadarOnline, “Nicole is devastated and humiliated by the rumors. She’s extremely image-focused and hates people whispering about her marriage behind her back.”

Another insider explained that Kidman “tried hard to save the marriage” but felt “Keith threw it all back in her face.”

Publicly, the country star’s behavior also seems to have shifted. “Keith looks as if he’s out to try to publicly embarrass and hurt Nic,” one source close to Kidman said. “This is a total 180 from the Keith I know. Changing the lyrics in the song he wrote for her and making it a dedication to Maggie says everything.”

Friends of the former couple are reportedly furious with Urban’s choices. “There’s a lot of anger and disbelief directed toward Keith right now,” one insider said. “People can’t believe he’d blow up the best thing that ever happened to him.”

The Custody and the Prenup

While the personal drama unfolds, the legal side seems more straightforward. The couple, who share daughters Sunday Rose (17) and Faith Margaret (14), have reportedly already agreed to custody terms.

Their prenuptial agreement is expected to simplify the division of assets. RadarOnline previously reported that under their prenup, Kidman agreed to pay Urban $600,000 for every year of marriage he remained sober. This clause may now play a role in the settlement.

An “Open Secret” No More

What’s perhaps most shocking to many fans isn’t just the rumored affair, but the suggestion that their open marriage was known in the entertainment world. For years, Kidman and Urban have been considered one of Hollywood’s most enduring couples. Married since 2006, they projected a polished image of a loving, supportive relationship — attending premieres hand-in-hand and walking red carpets together.

But behind the smiles, insiders claim, was a much different reality. According to sources, their arrangement allowed each to pursue their own personal lives quietly. For a long time, it worked. But eventually, the cracks began to show.

A New Chapter — Publicly

Urban’s alleged willingness to take his relationship with Baugh into the public eye may have been the breaking point. “He wasn’t afraid to come out of the shadows anymore,” said one insider. “He was tired of the facade.”

For Kidman, who has carefully maintained her public image for decades, this may have felt like betrayal on multiple levels — personal, emotional, and professional.

As of now, neither Kidman nor Urban has publicly confirmed any of the allegations about their marriage arrangement or Urban’s rumored new relationship. Baugh has also stayed silent.

Fans React

On social media, fans have been buzzing about the situation. Some have expressed shock at the idea of a long-open marriage, while others say it simply confirms what has been whispered about for years in Nashville and Hollywood circles.

Supporters of Kidman have flooded comment sections with words of encouragement, calling her “graceful” and “strong.” Meanwhile, others have criticized Urban for what they perceive as public disrespect.

What’s Next?

If the reports are true, this high-profile split could soon become one of the most talked-about celebrity divorces of the year. The combination of an alleged open marriage, a younger guitarist, and an image-conscious Hollywood star is a recipe for relentless media attention.

While some sources close to Urban say he’s “ready to move on,” others claim Kidman may not be done controlling the narrative. As the divorce proceedings continue, more details about their private lives may come to light.

Whether the rumors are fully true or just Hollywood whispers amplified, one thing’s certain: the fairytale image of Kidman and Urban’s marriage has shattered — and fans everywhere are watching what happens next.
