'It was such an amazing experience,' Nadia told The Herald Sun.
'I was totally out of my comfort zone performing on stage.
'I kept thinking about the reason why I was doing it; to raise awareness for breast cancer.'
The blogger also spoke to the Herald Sun on Tuesday about her "difficult month" after reports surfaced that Jimmy had been in a relationship with British based Australian socialite, Lauren Mand.
"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 told the Herald Sun.
"My single focus now is to continue to protect, care and provide for my two beautiful boys as this is a personal matter."
