"Although I'm heartbroken, I don't want to comment specifically on what's been reported about Jim's trip to the UK as I don't think that is in anyone's interests," Nadia said.
"My single focus now is to continue to protect, care and provide for my two beautiful boys as this is a personal matter."
While Nadia hesitated to discuss her former partner's new relationship, a friend told the publication that she discovered Jimmy's new romance with Lauren through text message.
Lauren Mand (in red) is said to be dating Jimmy Bartel.

Yesterday, new details emerged about Jimmy and Nadia Bartel's shock split.
The New Daily quoted a source as saying, "The truth will come out eventually, but I'm not saying any more than that."
"It's a cliché, but it's all really out of the blue."
The news comes after whispers that the blogger has sat down for a tell-all interview.
