During a piece-to-camera, the mother of two appeared to tear up as she mentioned their relationship breakdown, calling it “so painful.”
“It's been a tough time personally for me recently. It's just so painful,” the 34-year-old said as footage and photos of the young family aired.

Nadia seemed to well up momentarily, before continuing to discuss her appearance in the charity burlesque show.
“I'm hoping with Ladies' Night it will give me more confidence,” she admitted with a smile. “Obviously we're there for the cause, but I think it will be great for me to put myself out there, doing something that is definitely totally out of my comfort zone. I think it will give me a whole new load of confidence.”
According to the Herald Sun, it was originally claimed that former AFL star Jimmy would be edited out of the Channel Seven program.
“He will have to be edited from Ladies' Night. He was in the audience and he was definitely in cutaways,” an insider told the publication.
Indeed, the 35-year-old did not make an appearance in last night’s show (aside from his silhouette in a fireworks display towards the end).
Nadia had her personal life exposed in the media after the end of her marriage to Jimmy Bartel amid allegations of an affair with another woman.
However, stripping down just four months after giving birth to their second son Henley (son Aston is 3) was relatively easy for the Instagram star and fashion label owner.
The former AFL WAG told Who that she drew strength from the survivor stories of Rachelle Panitz, Founder and Managing Director of So Brave, and Tina Doueihi, who has modelled for the calendar and is an ambassador for the National Breast Cancer Foundation.
“Their stories were beautiful and just so incredible. You don’t realise that [breast cancer] can affect so many young women as well – and neither of those women have a family history, either,” Nadia said.
