While it's unclear what the two women— who attended Coachella together last year— were discussing, the Daily Mail suggested the topic of conversation surrounded her ex-husband's new girlfriend, Lauren Mand.
Over the weekend the Melbourne socialite confirmed rumours of their romance when she shared a photo showing the pair cuddling while walking down the street. Although she recently made it known they were officially an item, an old photo has since emerged with a caption that suggests she was secretly dating Jimmy while he was still married to the mother of his two sons.
Three months ago, while Lauren was living in London and Jimmy was travelling around the UK, she said she was "undecided but in love". While the post may seem irrelevant, knowing Lauren had already moved there when Jimmy visited the British capital adds more weight to Nadia's previous comments about his holiday.
"I don't want to comment specifically on what's been reported about Jim's trip to the UK as I don't think it's in anyone's interest," Nadia told the Herald Sun, all but confirming she knew he'd spent time with Lauren while travelling abroad.
While Lauren is yet to address the rumours or set the record straight, her friends have been rallying around her amid the intensifying drama, flocking to social media to praise her for finally going public with her romance.
"So happy for you, my darling Loz," one pal wrote underneath a photo of the couple. "Good to see you guys happy and enjoying life."
Another wrote: "Really happy for you, love that you kept it classy."
Not surprisingly, many took exception to the glowing comments, however, her pals were there to defend her: "Why can't we be happy for two people who clearly found genuine love and support in each other? She makes him look really happy. No one will know how long ago the love left that last relationship," she said, referring to Jimmy and Nadia's marriage.
"Don't be bitter. It's not always the man's fault, wives push men away all the time."
Another one of Lauren's loyal followers weighed in, taking the opportunity to blast Nadia, despite the fact the person defending her had already deleted her comment.
"And a vacuous, self-absorbed, selfish wife too, Jimmy deserves to be loved and adored. Nadia will be fine, she loves and adores herself."
