The radio hosts then asked the duo about this weekend's Logies, where the Today show hosts will be joined by Karl's brother, Peter Stefanovic.
On the topic of Pete, Langbroek asked, 'Have you made up after your Ubergate thing.'
'No,' Karl replied.
'Are you really shady at him?' Langbroek further grilled.
'Nah, he’s just a s**t of a brother and a shocking person,' Stefanovic said. 'He’s irresponsible.'
In the 'Ubergate' phone call, Stefanovic was overheard by an Uber driver who later exclusively talked to New Idea.
In the call, Karl accused Gardner of 'sitting on the fence' and not having enough opinions.
The driver told New Idea that Stefanovic became angry as he asserted that Gardner needed to 'step up' if she 'wanted to stay on the show.'
Speaking on Hughesy & Kate, Stefanovic said: 'Georgie was so incredibly good about that…I thought she was going to hit me.'
'I remember thinking to myself, ‘Gee, I wonder who that is?’ And then it became apparent it was us,' Gardner said, recalling reading a vague article about a 'war at breakfast.'
