However, according to The Daily Telegraph, Karl can relax, as a spokesperson for Channel Ten confirmed to the publication that Cass will not attend the event with the Network.
Awards organisers also told the Telegraph Cass was not on the guest list.
Even Cass has confirmed she won't be flying to the Gold Coast for the TV event.
“You’re hilarious,” she told The Daily Telegraph when questioned about her attendance.
“I’m not network talent just a regular panellist on studio 10. I used to go because gold Logie winners get two tickets for life.”
Studio 10's Sarah Harris has recently jumped to Cass's defence over accusations she's a "scorned woman" after her marriage breakdown.
"It must be very hard to front up and then always being questioned about your very famous ex-husband. She genuinely wants to move on," Sarah told Kyle and Jackie O.
Karl has moved on from his relationship with Cass, and is now married to Jasmine Yarbrough, 34, who he wed in December 2018.
