In what seemed to be a 'heated exchange', the pair spent the majority of their three-hour meeting 'clearly frustrated, speaking in hushed tones' - a vast contrast to the camaraderie they have portrayed to their followers.
'They were frosty,' says our eyewitness. That selfie was just for show. That lunch was very intense and neither of them seemed very friendly toward one another.
In what was apparently their first catch up since Lisa quit Today after she was refused the same pay as Karl, the pair took to Instagram with a beaming selfie as evidence that their friendship had survived the bitter salary feud. But according to onlookers at Cafe Sydney, there appeared to be no love lost between the former co-workers.
'At first they seemed to be trying to clear the air and move on from everything that's been said and done, but the longer it went on, the more terse their exchange became,' says the spy.
'Poor Lisa looked really frustrated and they didn't look like they were agreeing on much at all, maybe it was still too soon.'
It was only halfway through the surprising scene that the breakfast television stars were joined by Lisa's husband Peter FitzSimons, who stepped in to defuse the fiery exchange.
It was also during this time that the former rugby player asked the duo to post for the photo. Lisa later posted it on Instagram, with the caption: 'The best lunch today with this guy.'
