A woman was told live on the radio that her husband had a registered account with the website, Ashley Madison.
Sydney woman Jo called the station after Nova 969 radio hosts Fitzy and Wippa encouraged any listeners who had doubts about their spouse's loyalty to call in.
"When that thing came on the news about Ashley Madison, he went a bit funny," she said.
"I asked him, he said, 'Don't be stupid, we're married, we've got two kids.'"
Before the chat, Jo supplied the station with her husband's details so they could check to see if he had an account.
When it was revealed that he did, Jo was obviously distraught. She struggled to stop herself from swearing, and then hung up after calling the website "disgusting".
