Nicole Kidman's Husband's Flirty Move With His 25-Year Old Guitarist Slammed: 'So Trashy To Do This'

Keith Urban has set tongues wagging after a clip of him being flirty and singing to his touring guitarist emerged online.

Urban and his estranged wife, Nicole Kidman, faced rumors of marital troubles amid her solo living arrangements, with the actress filing for divorce after reportedly trying to save their marriage.

Reports claiming the country music star has moved on "with another woman" recently surfaced, with insiders saying Nicole Kidman is "still shocked over it."

Urban shared a flirty onstage moment with his guitarist, Maggie Baugh, before his marriage to Nicole Kidman hit the rocks.

In a new clip obtained by TMZ, Urban can be seen singing his 2016 hit "The Fighter" to the 25-year-old rising country star during his April 1st performance at Mandalay Bay in Las Vegas.

Fans couldn't help but notice his lovey-dovey gesture as he glanced and pointed at her when he sang "I was born to love you."

Baugh then grabbed her microphone and sang next to him until the song was over, after which they hugged warmly.

Urban has now left fans angry after he changed the lyrics to the song to name-drop Baugh.

In the song, which was inspired by his relationship with Kidman, he initially sang "When they're tryna get to you, baby, I'll be the fighter."

However, in an Instagram video that Baugh uploaded on Sunday, Urban sang, "When they're tryna get to you, Maggie, I'll be your guitar player."

According to Page Six, he explained back in 2017 that he wrote the song "very quickly" because he "literally just thought about Nic … and [their] relationship at the beginning and some of the things [they'd] said."

Urban's change of tone was met with mixed reactions from fans, as some bashed him for changing the lyrics to a song inspired by his estranged wife.

"It is so trashy to do this to a song inspired by his wife. It's the ultimate ick," an Instagram user wrote, while another added, "Show some class, Keith, for goodness sake!"

One irritated user wrote, "I'm no longer a Keith Urban fan. Everything and what he stood for is a lie. He should be ashamed of himself. Poor daughters."

"Sadly, she stuck by you when you were 4 months into your marriage and going to rehab. Short memory and you have poor taste and judgement," another fan wrote.

However, another user mentioned that Urban had a habit of changing the lyrics to the name of "whichever person is performing the song with him."

"I can't believe all these comments," a fan added. "Ladies, he always changes the lyrics when in other states and situations. He did it with Carrie Underwood, too. We have no idea what it was like living with Nicole."

Urban and Kidman raised eyebrows for a long time about the state of their marriage as they went months apart from each other.

The talks intensified when the actress filed for a residency permit in Portugal without the "Kiss a Girl" singer, as well as reports claiming she has been staying alone in a luxury Hampstead mansion that costs £65,000 [$88,000] per month.

Kidman has now filed to end their 19-year marriage as multiple sources told TMZ that they've been living separately "since the beginning of summer."

Urban, who has been traveling on tour, has since moved out of their family home in Nashville, Tennessee, and bought another one in the same city. A source told the news outlet that the actress has been taking care of their two children, Sunday Rose and Faith Margaret.

"[Kidman is] holding the family together through this difficult time since Keith has been gone," a source said.

"Sometimes relationships just run their course," a different source told Page Six, adding that Kidman "did not want the separation and was trying to save things."

Meanwhile, rumors are circulating, suggesting that Urban has already moved on and is "with another woman" just days after his split from Kidman became public knowledge.

"All the signs point to the fact that Keith is with another woman," several sources close to the "Big Little Lies" actress told TMZ.

"Let's just say, Nicole doesn't dispute that, but she's still shocked over it," they added, per The Blast.

One insider even explained that Urban's new romance "is all over Nashville." It remains unclear if Urban moved on with the unidentified woman before or after his separation from Kidman.

Although there are talks that the singer may have been unfaithful, the reason behind their split is not yet known.
