They've always defended their marriage against rumors of a split, and the newest batch of reports about their relationship could somewhat back up Keith Urban and Nicole Kidman's claims of a happy relationship. 

Keith Urban Calls Marriage A 'Priority'

According to OK! Magazine, the couple have one very big thing in common these days-botox. And according to their sources, the Oscar winning actress is the one who turned her husband on to the cosmetic procedure, and now, he's determined to keep using it so he can keep his youthful looks. 

"He is getting Radiesse fillers, because he's determined to keep that baby face his female fans love," sources said.  

Rumors Swirl About Keith Urban & Kelsea Ballerini

In addition, the idea of being the more youthful one in the romance has supposedly turned it into a competition between the two, with Kidman allegedly increasing her injection regime and can barely move her face anymore, and now, family and friends are worried that they're both going overboard. 

"People are worried, but it's too awkward to bring up," the sources said. 

The new rumors come on the heels of reports that urban was getting to close to his current tour's opening act, Kelsea Ballerini, last month, which caused his wife to flip out, a report her reps have since denied. 

Urban also seemed to speak out against the rumors recently as well, admitting he and his wife work on their marriage every day, but because it's their biggest priority and one of their favorite things to focus on as a couple.  

"It's our priority, you know? It's what we love to do more than anything in the world," he said.
