The insider also clarified that, despite their history, Tarek and Christina, 38, don't have much of a connection outside of their popular home-flipping series.
'They're exes who share a history and children and a workplace, but outside of coparenting, they're not friends,' they added.
The confrontation between the former couple was set off because Tarek was annoyed at how Christina signaled that she and the rest of the crew were ready to begin filming a scene, TMZ reported on Tuesday.
He allegedly took the credit for Christina's success and called the mother of his children a 'washed-up loser.'
He also reportedly shouted, 'Look at me, look at me, look at me. It’s called winning,' and, 'The world knows you're crazy!'

Tarek also brought his fiancée Heather Rae Young, 33, into the argument by saying she was 'hotter' and 'richer' than his ex.
On Thursday, Christina seemed to signal that things were again running smoothly on the series when she shared a short clip of crew working.
'Nice day on the Flip Or Flop set,' she wrote.
They on-set confrontation with Christina occurred shortly after she went public with her romance to new boyfriend Joshua Hall and opened up about a psychedelic trip brought on by smoking toad venom.
According to a source close to him, he was primed to lose his cool because he was angry about learning of the drug trip, which occurred before Christina hooked up with her new man.
Tarek's outburst appears to have come shortly before a break in filming, as Heather revealed on Wednesday that the couple had jetted off to St. Barts for a romantic getaway.
She shared a photo to her Instagram Stories of herself enjoying 'Breakfast with my sweet love' at the upscale Nikki Beach resort.
