The rumors concerning the state of Keith Urban and Nicole Kidman's marriage don't seem to be letting up, and as the pair reportedly struggle to overcome them and save their 10-year union, new reports have emerged which allege that Urban may have had an affair with former flame Joni Wilson.

According to New Idea Magazine (via The Daily Mail), Urban has previously met up with his old flame, Joni Wilson, for "Coffee dates," and Wilson has even penned a song for him that was sexy.

"My song was about calling your boss to say you're not coming in for the day-you're staying at home with your lover and having sex," Wilson allegedly told the magazine. "I thought it would be perfect for Keith, being a sexy love song."

Wilson and Urban met back in the 1990s, but she reportedly claimed to meet up with him more recently, though no dates have been specified and it's unclear if he was married to Kidman at the time. However, the magazine does maintain that Urban is often flirty while on the road, and he keeps in contact with exes, something that it says Kidman should be more alert to.

"Joni is not the only former flame Keith keeps in touch with, he's very flirty when he's on tour and Nicole's not there to keep an eye on him," a source said.

This new report comes after the pair, who have made a show in public recently of their love, were reportedly enrolled in a retreat that was a rumored last effort to save the marriage.

"Nicole and Keith have been battling problems for a long time now and it's gotten to the point where it's make or break," a source said. "Nicole has told friends they're giving their marriage three months and have decided to go their separate ways and consciously uncouple if they can't work through their problems."

Urban himself has even spoken out against rumors of the marriage being on the rocks, saying the stories were made up often because they lived their lived out of the spotlight as much as they could, with a home base in Nashville.

"People make up the most insane crap and we kind of just roll with it," he said at the time. "I want to live our life together and the fact we live somewhere where we're not being photographed all the time-it makes it possible to make up that stuff because you're not always there to defend it."
