Producer predicts Kylie and Jackie O split.

A former radio producer has made a sobering prediction about the future of and in the wake of their shock breakfast show collapse.

ARN announced on Tuesday that Henderson's $100million contract had been terminated after she told executives she 'cannot continue to work with Mr Kyle Sandilands' following his harsh comments on air that left her in tears.

Sandilands has also been suspended and given 14 days to remedy the breach, otherwise facing termination, while Henderson has been offered the possibility of hosting an alternative show on the network. 

Christian Hull, who was previously a national digital producer for Southern Cross Austereo, weighed in on the drama on Wednesday, claiming the pair's professional, and personal relationship, is unlikely to recover.

Taking to , Hull, 39, who has worked with the likes of and , and and Harley Breen, dismissed 

'For those wondering if The Kyle & Jackie O Show is just doing a publicity stunt, I can pretty much guarantee that this is the end of the show,' Christian said.

'The show is over, it's done. I don't think you'll ever see Kyle and Jackie in a room talking to each other again.'

Christian, who branched out into comedy, podcasting, and social media content creation after his stint in radio, also made a startling prediction about the future of ARN, KIIS FM's parent company.

'It's really interesting to see what's going to happen now that the show has finished,' he said.

'It's my belief that, once Kyle and Jackie O finishes the show, ARN is done. There's no one that can replace them, and I just don't think radio will ever be the same.'

Christian, who credited the iconic duo for inspiring his own career in radio, said that he thought the clash was a storm in a teacup, until ARN released a statement to shareholders on Tuesday afternoon.      

'I thought: "There's no way – they'll have a little on-air tiff, they'll have a break, they'll recover and they'll move forward,"' he said.

'And then, late yesterday, they released information to all the shareholders of ARN, and when you're talking to shareholders you know s***'s going down. 

'That was the moment I knew: "Holy s***, this is legitimate."'

The Kyle & Jackie O Show collapsed on Tuesday amid a high-profile feud between hosts Henderson and Sandilands.
