Nicole Kidman is, allegedly, worried that LeAnn Rimes could hit on her husband, Keith Urban.

Urban recently revealed that Rimes is one of the artists that he wants to collaborate with this coming New Year. However, his response didn’t, allegedly, sit well with his wife.

In the Dec. 7 issue of New Idea, a source claimed that Kidman asked Urban to cut ties with Rimes.

After all, the Big Little Lies star is aware that Rimes is married to Eddie Cibrian, with who the singer previously had an affair.

Kidman is, allegedly, worried that Rimes and Urban could also have an affair. And the artists could, allegedly, end up together just like what happened to the singer and her husband.

“The fact LeAnn has this history has Nicole on high alert when she’s around – and it’s meant Keith has to abandon any dreams of working with LeAnn again,” the source said.

However, this isn’t where the tabloid’s claims ended. They also said that Rimes seemed flirty towards Urban when they first worked together years ago.

Back then, Rimes was just 21 years old. And an interviewer told her that Urban has a reputation for being a flirt.

Rimes replied by saying that Rimes could maybe show her a good time.

The comment is still fresh in Kidman’s ears even though Urban said that he barely remembers what it was like working with Rimes.

According to the insider, it’s also possible that Rimes and Urban had an affair. But the country singer is just denying it.

The source also said that the American Idol judge didn’t realize that Kidman has such strong feelings about him and Rimes working together.

Urban has, allegedly, apologized to Kidman several times. But the only thing that will make his wife happy is if he never works with Rimes again.

Tabloids have been depicting Kidman as a jealous wife in recent years.

Earlier this year, Woman’s Day claimed the Kidman asked Jennifer Lopez to stay away from Urban.

The actress, allegedly, knows how close Urban and Lopez were while judging in American Idol. And Kidman is worried that their closeness would extend to their private lives.

In related news, Woman’s Day also previously claimed that Urban is jealous of Hugh Grant.

A source told the tabloid that Urban was upset when Kidman posted a loved-up photo of herself with Grant without informing him first.

However, none of these claims are correct.
